Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) says: Do not try to overpower this night (that is, do not keep worshipping all night), for you are not able to do so. When any of you becomes drowsy, he should go to his bed; this will be safer for him.
This narration was recorded by Imam al-Tabarani in al-Mu'jam al-Kabir, and its narrators are the narrators of the "Sahih".
