Ibn Abbas reported: The Prophet (ﷺ) said, “No good deed is better than what is done on these first ten days of Dhul-Hijjah.” Some companions of the Prophet said, “Not even jihad in the cause of Allah?”
The Prophet said, “Not even jihad in the cause of Allah, except in the case of a man who goes out with his life and wealth in danger and returns with nothing"
(Sahih al-Bukhari Vol. 2, Book 15, Hadith 86 {926})
So the Muslim should start these days with sincere repentance to Allaah, then he should do a lot of righteous deeds in general, then he should pay attention to doing the following deeds:
1. Fasting
It is Sunnah for the Muslim to fast on the first nine days of Dhu’l-Hijjah, because the Prophet (peace and blessings of Allah be upon him) encouraged us to do righteous
deeds in the first ten days of Dhu’l-Hijjah, and fasting is one of the best of deeds, which Allaah has chosen for Himself as it says in the hadeeth qudsi: “Allaah says: ‘All the deeds of the son of Adam are for him, except fasting, which is for Me and I shall reward for it.” Narrated by al-
Bukhaari, 1805.
The Prophet (peace and blessings of Allaah be upon him) used to fast on the first nine days of Dhu’l-Hijjah. It was narrated from Hunaydah ibn Khaalid from his wife, that one of the wives of the Prophet (peace and
blessings of Allaah be upon him) said: The Prophet (peace and blessings of Allaah be upon him) used to fast on the first nine days of Dhu’l-Hijjah and the day of ‘Ashoora’, and three days each month, the first Monday of the month and two Thursdays. Narrated by al-Nasaa’i, 4/205 and by Abu Dawood; classed as saheeh by
al-Albaani in Saheeh Abi Dawood , 2/462.
2. Reciting tahmeed, tahleel and takbeer
It is Sunnah to recite takbeer (saying
Allaahu akbar (Allaah is most great)),
tahmeed (saying al-hamdu Lillah (praise be to Allaah)), tahleel (saying Laa ilaaha ill-Allaah (There is no god but Allaah)) and tasbeeh (saying Subhaan-Allaah (Glory be to Allaah)).
It was narrated from ‘Abd-Allaah ibn
‘Umar (may Allaah be pleased with him) that the Prophet (peace and blessings of Allaah be upon him) said: “There are no days that are greater before Allaah or in which good deeds are more beloved to Him, than these ten days, so recite a great deal of tahleel, takbeer and tahmeed during them.” Narrated by Ahmad, 7/224;
its isnaad was classed as saheeh by
Ahmad Shaakir.
The takbeer is as follows:
Allaah akbar, Allaahu akbar, laa ilaaha ill-
Allaah, Allaahu akbar, wa Lillaah il-hamd
Translation: (Allaah is Most Great, Allaah is Most Great, there is no god but Allaah; Allaah is
Most Great and to Allaah be praise).
And there are other versions.
3. Doing Hajj and ‘Umrah
One of the greatest deeds that can be done during these ten days is Hajj to the sacred House of Allaah. Whoever Allaah helps to go on Hajj to His House and do the rituals in the required manner will in sha Allaah
be included in the words of the
Messenger of Allaah (peace and blessings of Allaah be upon him): “An accepted Hajj brings no less a reward than Paradise.”
4. Udhiyah (sacrifice)
One of the righteous deeds that bring a person closer to Allaah in these ten days is to slaughter the sacrifice and to look for a good, fat animal and to spend money on it for the sake of Allaah.
Let us hasten to make the most of these great days, before the negligent regrets what he did, and before he asks to go back and receives no response.
5. READING THE QUR’AN
we should try to schedule it in all our activities because prophet Muhammad PBOH said "fasting & Qur’an will intercede in the day of kiyamah" [AHMAD]
6. GOOD SPEECH
Prophet Muhammad PBOH said "every good /nice speech there ‘s reward for it and it’s regarded as sadaqah" [BHAIHAQY]
7. ATTENDING MAJALIS/TAFASEERS/LECTURES IN THE MASJID
The prophet PBUH said "Whoever goes to masjid not desiring except to learn out to teach what is good has the reward of pilgrimage/hajj (Bhaihagy)
8. Be dutiful to your parents, because one of the major sin
after shirk is being undutiful to the parents.
9. In these days, visit patients, old relatives
10. Feed the poor and the needy
12. Do Dawah and guide the Non Muslim brothers to truth, even a verse.
CONCLUSIVELY: Verily all the above listed deeds are what an ideal must suppose to do in these golden ten days and also beyond it so as to be among those that Allah will save from the hellfire to the jannah.
Brothers and sisters why don’t you use this time in doing good deed that will help you here and there after (i.e. fid-dunya wal’akhira)
