عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا أَنَّهَا فَقَدَتِ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ مِنْ مَضْجَعِهِ فَلَمَسَتْهُ بِيَدِهَا فَوَقَعَتْ عَلَيْهِ وَهُوَ سَاجِدٌ وَهُوَ يَقُولُ: ((رَبِّ أَعْطِ نَفْسِي تَقْوَاهَا، زَكِّهَا أَنْتَ خَيْرُ مَنْ زَكَّاهَا، أَنْتَ وَلِيُّهَا وَمَوْلَاهَا))
Sayyidah Aisha (may Allah be pleased with her) narrates that she found the Prophet Muhammad (peace and blessings be upon him) missing from the bed, so she searched for him with her hand. When her hand touched him, she realized that the Prophet (peace and blessings be upon him) was in the state of prostration and was supplicating: "O my Lord! Grant my soul its piety, purify it, You are the best to purify it, You are its Guardian and Master."
