The last ten verses of Surat Aal-Imraan
Ibn ‘Abbaas (radi Allahu anhu) said that that he stayed one night with Maymoonah (radi Allahu anha), the Mother of the Believers, who was his maternal aunt. He said: The Messenger of Allah (sal Allahu alaihi wa sallam) slept until halfway through the night, or just before or after that. The Messenger of Allah (sal Allahu alaihi wa sallam) woke up and started wiping the sleep from his face with his hand. Then he recited the last ten verses of Soorat Aal-Imraan, then he got up and went to a waterskin that was hanging there, and did wudoo’ from it and did it well, then he stood and prayed.
[Sahih Al-Bukhari and Muslim]
We learn from the above Hadith the virtue of these verses. Imam Al-Nawawi (may Allah have mercy on him) said: This indicates that it is mustahabb to recite these verses when getting up from sleep.
And Allah knows best!
