al-bosniy:

Shaykh-ul-Islām Ibn Taymiyyah was asked:

Which one of them is better; The 10 days of Dhul-Ḥijjah or the last 10 days of Ramaḍān?

So he Raḥimahullāh answered:

“The first 10 days of Dhul-Ḥijjah are better and more virtous than the 10 days of Ramaḍān and the last 10 nights of Ramaḍān are better and more virtous than the 10 nights of Dhul-Ḥijjah.”
