The Best Deeds in the Last Ten Days of Ramadan

Question:
The questioner says: Honorable Shaykh, what are the best deeds, in order of preference, in the last ten days of Ramadan? May Allah reward you with good. The best deeds, in order of preference, in the last ten days?

Answer:
The best deeds are what the Messenger (peace and blessings be upon him) used to do in these ten days? Keeping the nights awake, and i'tikaf (spiritual retreat in the mosque) in them. And prayer, and tahajjud (the late-night voluntary prayer) in them? And frequent recitation of the Qur'an, seeking forgiveness, dhikr (the remembrance of Allah), saying Allahu Akbar, tasbih, and tahmid.
He (peace and blessings be upon him) used to sit in the mosque and sleep. He did not perform i'tikaf (spiritual retreat in the mosque) in the mosque in order to sleep or in order to rest. Rather, he performed i'tikaf (spiritual retreat in the mosque) in the mosque to devote himself to worship. He occupied all his time in worship, except for what he needed for rest, or for eating and drinking. Otherwise, most of his time was in worship, peace and blessings be upon him. Yes.
