ذِكْرُ الْبَيَانِ بِأَنَّ قَوْلَهُ ﷺ «غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ» أَرَادَ بِهِ مِنَ الصَّلَاةِ إِلَى الصَّلَاةِ
I heard Humran bin Aban tell Abu Burdah in the mosque of Basrah, when I was standing next to him, that he heard ʿUthman bin ʿAffan ؓ narrating from the Prophet ﷺ that he said: ʿWhoever does wudoo’ properly as enjoined by Allah, may He be glorified and exalted, the five prayers will be an expiation for whatever comes in between them.ʿ (Using translation from Aḥmad 473)
عَنِ النَّبِيِّ ﷺ قَالَ «مَنْ أَتَمَّ الْوُضُوءَ كَمَا أَمَرَهُ اللَّهُ جَلَّ وَعَلَا فَالصَّلَوَاتُ الْخَمْسُ كَفَّارَةٌ لِمَا بَيْنَهُنَّ»
