Bismillaah:

Alhamdulillaah, the blessed days are here one more time..!
The glorious days when rewards are multiplied many times, and sins are forgiven the days in which Allaah عزوجل gives us yet another chance to worship Him and correct our faults and make up for our shortcomings.

Abdullaah Ibn Abbas رضي اللّه عنه said.

The Messenger of Allaah صلي الله عليه وسلم said:

“There are no days in which the righteous acts are more beloved to Allaah than in these days, meaning the ten days of [ Dhul Hijjah] . They asked: O Messenger of Allaah صلي الله عليه وسلم not even fighting in Allaah's way? He صلي الله عليه وسلم replied: Not even fighting in Allaah's way except for the man that goes out with his life and his money and does not return with either of them”.

Takhreej:

{ Imam Al Bukhari and Muslim in their Saheeh }

AI Hafiz bn Hajr رحمه الله commented:

“The apparent reason as to why the ten days of Dhul-Hijjah stand out in their virtue is the fact that they combine in them the performance of the most essential acts of worship, which are salah, fasting, charity, and Hajj (pilgrimage), and we do not find this trait present in any other set of days.”

{ Fath ul Bari Sharh Saheeh al Bukhari }

So just like we worked hard in the last ten nights of Ramadan, and gave it all we got, we should be doing the same for the first ten days of Dhul Hijjah.

*** And Allaah عزوجل has the best knowledge ***
