عَنْ أُمِّ أَيُّوبَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ نَزَلَ الْقُرْآنُ عَلَى سَبْعَةِ أَحْرُفٍ أَيُّهَا قَرَأْتِ أَجْزَأَكِ
Sayyidah Umm Ayyub (may Allah be pleased with her) narrates that the Noble Prophet (peace and blessings be upon him) said to her: The Noble Qur’an has been revealed in seven modes of recitation; whichever of them you recite will suffice for you.
