Below is a transcription of a lecture on how to benefit from the blessed days of Dhul-Hijjah by Umm ‘Abdur-Rahmân. May Allâh reward the sister who transcribed the lecture and sent it as a contribution to be placed on this blog:
“By the ten nights.” [Al- Fajr 89:2]
The “ten nights” which Allâh [subhâna wa ta’âlâ] is swearing by here, are the first 10 days of Dhul-Hijjah.  Allâh [subhâna wa ta’âlâ] swears an oath by them, and swearing an oath by something is indicative of its importance and great benefit.
Ibn ‘Abbâs [radi Allâhu ‘anhu] narrated that Prophet [sall-Allâhu ‘alayhi wa sallam] said: “There is no deed more precious in the sight of Allâh, or greater in reward, than a good deed done during the ten days of Sacrifice.” He was asked: “Not even jihâd for the sake of Allâh?” He said: “Not even jihâd for the sake of Allâh, except in the case of a man who went out to fight giving himself and his wealth up for the cause, and came back with nothing.” 
So, my sisters [and brothers] take note of the following:
Have the intention to spread this important information.
It is a great chance to collect uncountable hasanât [rewards].
It is a great chance to renew your relation with Allâh [subhâna wa ta’âlâ].
Prepare now so you can start from the first night/day of the month [i.e. as soon as Dhul-Hijjah is announced]. You don’t want to miss a moment of the best days in the sight of Allâh [subhâna wa ta’âlâ].
Since the Prophet [sall-Allâhu ‘alayhi wa sallam] referred to the 10 days of Dhul-Hijjah as: “…no days better than these days in the sight of Allâh.” , the scholars have said that these are better than Ramadan.  Therefore, be very vigilant and don’t waste these precious moments. Ask Allâh to help you to benefit from this period of His special Grace.
Ask yourself these questions [non-rhetorical]:
Did you intend to benefit from these days?
What have you done to prepare for these 10 days?
Did you prepare a program?
What is your plan of action?
Here is a brief guide to help you to prepare for the best days of the year [inspired by a lecture by Shaykh Muhammad Hassan Yâqûb]:
