[12].Surah Yusuf [Joseph] :Ayat 18

Ayat 18. And they brought his shirt stained with false blood. He said: "Nay, but your ownselves have made up a tale. So (for me) patience is most fitting. And it is Allah (Alone) Whose help can be sought against that which you assert."   

Hazrat Ibn Abbas (May Allah be pleased with them) reported: The Messenger of Allah  [SAWW](PBUH) said, "There are no days during which the righteous action is so pleasing to Allah than these days (i.e., the first ten days of Dhul-Hijjah).'' He was asked: "O Messenger of Allah  [SAWW], not even Jihad in the Cause of Allah?'' He  [SAWW](PBUH) replied, "Not even Jihad in the Cause of Allah, except in case one goes forth with his life and his property and does not return with either of it.''

[Al-Bukhari Volume 02, Book 15, Hadith # 086]. 

Lesson : as mentioned above in Surah Yusuf Ayat 18. "And it is Allah (Alone) Whose help can be sought against that which you assert." This Hadith brings out the following two points: 1. Righteous deeds during the first ten days of the month of Dhul-Hijjah are far better and more rewarding than righteous deeds done on other days of the year, because they are Hajj days in the sacred season of pilgrimage. Because of their excellence and importance, Allah (SWT) swore by them, thus: "By the Dawn; by the ten Nights...'' (89:1,2)

2. Jihad has great eminence in Islam.
