ANOTHER SUPPLICATION TO BE OFFERED AFTER THE CALL TO PRAYER H 1056 "Whosoever, after hearing the call to prayer bears witness, 'I bear witness that there is none worthy of worship except Allah, the One, without associate and that Muhammad is His worshiper and Messenger; I am pleased with Allah as my Lord, with Muhammad as His Messenger and with Islam as my Religion,' will have his sins forgiven." R 1056 Muslim with a chain up to Sa'ad the son of Abi Waqkkas who related that the Messenger of Allah, praise and peace be upon him, said this.
1040- وعن سعدِ بن أَبي وقَّاصٍ رضي الله عنه ، عن النبي صلى الله عليه وآله وسلم ، أنَّه قَالَ : "مَنْ قَالَ حِيْنَ يَسْمَعُ المُؤَذِّنَ : أشْهَدُ أنْ لاَ إلَه إِلاَّ اللهُ وَحْدَهُ لاَ شَرِيكَ لَهُ ، وَأنَّ مُحَمَّداً عَبْدُهُ وَرَسُولُهُ ، رَضِيتُ بِاللهِ رَبّاً ، وَبِمُحَمَّدٍ رَسُولاً ، وَبِالإسْلامِ دِيناً ، غُفِرَ لَهُ ذَنْبُهُ" رواه مسلم .
