Aisha Allah be pleased with her narrates that when the Prophet, Allah send peace and blessings upon him would leave the toilet he would say:

We thank You Oh Allah

Note: There are two meanings which have been given by scholars for ‘Ghufranak’, one being ‘Oh Allah, we ask Your forgiveness’ and the other, ‘Oh Allah, we thank You’. To many, the second would seem more appropriate taking into consideration the fact that one has just relieved himself, and had Allah made this not possible, it could lead to many severe physical health problems or even death. Therefore the translation of thanking Allah would seem more appropriate on this occasion.

حَدَّثَنَا مُحَمَّدُ بْنُ إِسْمَاعِيلَ ، قَالَ : حَدَّثَنَا مَالِكُ بْنُ إِسْمَاعِيلَ ، عَنْ إِسْرَائِيلَ ، عَنْ يُوسُفَ بْنِ أَبِي بُرْدَةَ ، عَنْ أَبِيهِ ، عَنْ عَائِشَةَ قَالَتْ : كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا خَرَجَ مِنَ الْخَلاَءِ ، قَالَ :

غُفْرَانَكَ
