"I noticed that the Messenger of Allah ﷺ was missing from bed, so I started to look for him, and I thought that he had gone to one of his concubines. Then my hand fell on him when he was prostrating and saying: "Allahummaghfirli ma asrartu wa ma a'lant (O Allah, forgive me for what (sin) I have concealed and what I have done openly).'" (Using translation from Nasāʾī 1124)  

عَائِشَةُ فَقَدْتُ رَسُولَ اللهِ ﷺ مِنْ مَضْجَعِهِ فَجَعَلْتُ أَلْتَمِسُهُ وَظَنَنْتُ أَنَّهُ أَتَى بَعْضَ جَوَارِيهِ فَوَقَعَتْ يَدِي عَلَيْهِ وَهُوَ سَاجِدٌ يَقُولُ «اللهُمَّ اغْفِرْ لِي مَا أَسْرَرْتُ وَمَا أَعْلَنْتُ»
