7 Different Recitations

Narrated 'Umar bin Al-Khattab:

I heard Hisham bin Hakim bin Hizam reciting Surat-al-Furqan in a way different to that of mine. Allah's Apostle had taught it to me (in a different way). So, I was about to quarrel with him (during the prayer) but I waited till he finished, then I tied his garment round his neck and seized him by it and brought him to Allah's Apostle and said, "I have heard him reciting Surat-al-Furqan in a way different to the way you taught it to me." The Prophet ordered me to release him and asked Hisham to recite it. When he recited it, Allah s Apostle said, "It was revealed in this way." He then asked me to recite it. When I recited it, he said, "It was revealed in this way. The Qur'an has been revealed in seven different ways, so recite it in the way that is easier for you."(Bukhari 3:601)
