Month Dzulhijjah which is the final month of the Hijri year is one of glorious months that also must be known by Muslims of course. If you talk about this month, certainly in our minds will remember of Hajj and Eid Adha day on 10th Dzulhijjah. And also in Indonesia, this month known with events of eating roasted meat together and also month full of married being hold. Of course in Islam, month Dzulhijjah have noble position so alot of righteous deeds we can do and what a pity to miss it.
From Ibn 'Abbas r.a. that the Prophet said, "There are no days in which good deeds at that time was more beloved by Allah than these days, ie the ten days of the month Dzulhijjah." They asked, "O Messenger of Allah, not even jihad fi sabilillah?" He replied, "Not even jihad fi sabilillah, except those that came out (jihad) with the soul and money, then do not come back with anything." (Narrated by Bukhari)
From `Umar r.a., that the Prophet said, "There is no day of the most majestic and very loved by Allah to do good in it than this ten days (Dzulhijjah). Then in that time, we should be multiply tahlil, takbir, and tahmid." (Narrated by Ahmad)
As for some good deeds around the month Dzulhijjah are:
1. Hajj and ‘Umra. This is the most important deeds in the month of Dzulhijjah. None other hajj than in the month of Dzulhijjah. The rewards for those who can perform this is great in the sight of Allah. The Prophet said., "From 'Umrah to Umrah is a ransom (sins done) in between, and the Mabrur hajj the reward is no other than heaven."
2. Fasted for 10 days in the first days of the month Dzulhijjah, or in the part, or at least a day on the day of Arafah. Fasting is also the main deeds. Allah choose fasting as a servants’ practice for Him so that He alone that determines the reward. It is contained in a Hadith Qudsi. "Fasting is for Me, and I am the one who will reward. Indeed he has abandoned lust, food, and drink simply because of I am."
In a hadith narrated from Abu Said Al-Khudri ra, the Prophe said, "It is not a servant fasts in one day on the path of Allah, but Allah certainly would distanced him of that fasting from the fire of hell for seventy years long." (Hadith muttafaq 'alaih)
From Abu Qatadah r.a. that the Prophet said, "Fasting on the day of Arafah cause of expecting reward from Allah, merged the sins a year before and after". (Narrated by Muslim)
3. Do Takbir and dhikr. Expand takbir and dhikr in the first 10 days of the month Dzulhijjah as commanded by Allah Almighty, ".... And that they may mention the name of Allah on the specific days ...." [QS. Al-Hajj (20): 28]. The exegetes interpret the phrase "in the days specified" with the "ten days of the month of Dzulhijjah". Therefore, the scholars suggested us to expand our dhikr on those days. Moreover, there is the hadith of Ibn 'Umar that reinforce. It reads, "Then multiply in those days, tahlil, takbir, and tahmid". (Narrated by Ahmad)
Imam Bukhari said that Ibn 'Umar and Abu Hurayrah out to the market on the ten days while echoing takbir and then people started to follow them. It is narrated that the tabi’in in those days saying, "Allahu akbar, Allahu akbar, laa ilaha ilallah, walllahu akbar, Allahu akbar wa lillahil hamdu." That means, Allah is The Greatest, Allah is The Greatest, there is no God besides Allah. And Allah is the Greatest, Allah is the Greatest, all Praises to Allah."
Recommend to rise his voice when takbir as well as in mosques, homes, markets, or on the road. Allah says, "And to glorify Him in that He has guided you, and perchance ye shall be grateful.” [QS. Al-Baqarah (2): 185]
Expand repents and abandon all forms of vices and sins. Vices is the cause of the servants away from Allah. While the obedience is the door to get the love and mercy of Allah. And Allah have more love than the love of a servant toward Allah. Even Allah jealous if his servants commit vices or sins. From Abu Hurairah ra, the Prophet said, "Verily Allah is jealous, and the jealousy is when a servant do what Allah has forbidden to him." (Hadith muttafaq 'alaihi)
4. Expand good deeds. Not just the obligatory deeds alone. Because, Allah likes and loves a servant who closer him toward Allah by doing nawafil (practice of the Sunnah). We can multiply our sunnah salat, sadaqa, jihad, reading the Qur'an, and make doing good and avoiding evil. We really hope that all the practices can bring many rewards to us. But, we would more expect of receive love and pleasure of Allah.
5. Similarly we do muthlaq (absolute) takbir, at any time, day or night until the Eid salat and the takbir muqayyad. Takbir Muqayyad is performed after each obligatory salat performed by congregation. For those of us who are not on Hajj, Takbir starts from Dhuhr of Eid Adha day continues until Asr time on the Tasyriq day (11th,12th and 13th of Dzulhijjah).
6. Sacrifice. Can we do at the Feast of Sacrifice and Tasyriq days. This worship is the Sunnah from Prophet Ibrahim and Prophet Muhammad confirm it as a shari'ah for us. Word of the Prophet "Sacrifice by slaughtering two white and horned rams. Himself that slay them by call the name of Allah and do takbir, then put his foots beside the body of the sheep." (Hadith muttafaq 'alaihi).
7. Prohibited from removing or cutting of hair and nails for people who want to do sacrifice. Narrated by Muslim and others, from Umm Salamah that the Prophet said: "If you see the new moon month of Dzulhijjah and anyone of you want to make sacrifice, let him refrain from (cut) his hair and nails." In another narration, "then he should not take anything from his hair or nails that he do sacrifice."
This is to resemble of the people perform Hajj who leads the animal sacrifices. Word of Allah, "And don’t shave your (hair) heads until the offering (the animal) reaches the place of sacrifice." [QS. Al-Baqarah (2): 196]. This prohibition, according the sunnah, only reserved for those who sacrifice, not including his wife and children, unless each of them make sacrifice too.
8. Perform Eid Adha praying (salat) and listening to the sermons. In fact, childrens and women who have menstruation instructed by Prophet to attend the congregation prayers ied adha in the terrain to listen the sermons.
