"O Abu Ayyub, we missed the general mobilization, but we have been told that whoever prays in the four Masjids will be forgiven his sins." He said: "O son of my brother! I will tell you of something easier than that. I heard the Messenger of Allah ﷺ says: 'Whoever performs Wudu' as commanded and prays as commanded, will be forgiven for his previous actions.' Is it not so, O 'Uqbah?" He said: "Yes."
عَاصِمٌ يَا أَبَا أَيُّوبَ فَاتَنَا الْغَزْوُ الْعَامَ وَقَدْ أُخْبِرْنَا أَنَّهُ مَنْ صَلَّى فِي الْمَسَاجِدِ الأَرْبَعَةِ غُفِرَ لَهُ ذَنْبُهُ فَقَالَ يَا ابْنَ أَخِي أَدُلُّكَ عَلَى أَيْسَرَ مِنْ ذَلِكَ إِنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنْ تَوَضَّأَ كَمَا أُمِرَ وَصَلَّى كَمَا أُمِرَ غُفِرَ لَهُ مَا قَدَّمَ مِنْ عَمَلٍ أَكَذَلِكَ يَا عُقْبَةُ قَالَ نَعَمْ
