'Umar bin Khattab said: I heard Hisham bin Hakim bin Hizam reciting Surah al-Furqan in a style different from that in which I used to recite it, and in which Allah's Messenger ( صلی اللہ علیہ وسلم ) had taught me to recite it. I was about to dispute with him (on this style) but I delayed till he had finished that (the recitation). Then I caught hold of his cloak and brought him to the Messenger of Allah ( صلی اللہ علیہ وسلم ) and said: Messenger of Allah, I heard this man reciting Surah al-Furqan in a style different from the one in which you taught me to recite. Upon this the Messenger of Allah ( صلی اللہ علیہ وسلم ) told (me) to leave him alone and asked him to recite. He then recited in the style in which I beard him recite it. The Messenger of Allah ( صلی اللہ علیہ وسلم ) then said: Thus was it sent down. He then told me to recite and I recited it, and he said: Thus was it sent down. The Qur'an was sent down in seven dialects. So recite what seems easy there from.

This hadith has been transmitted thus by 'Umar bin Khattab (with a slight change of words):" I heard Hisham bin Hakim reciting Surah al-Furqan during the lifetime of Allah's Messenger ( صلی اللہ علیہ وسلم ) ." The rest is the same but with this addition:" I was about to catch hold of him in prayer, but I exercised patience till he pronounced salutation.

This hadith has been transmitted by Zuhri.

Ibn 'Abbas reported Allah's Messenger ( صلی اللہ علیہ وسلم ) as saying: Gabriel (ؑ) taught me to recite in one style. I replied to him and kept asking him to give more (styles), till he reached seven modes (of recitation). Ibn Shibab said: It has reached me that these seven styles are essentially one, not differing about what is permitted and what is forbidden.

This hadith has been narrated by Zuhri with the same chain of transmitters.

Ubayy bin Ka'b reported: I was in the mosque when a man entered and prayed and recited (the Qur'an) in a style to which I objected. Then another man entered (the mosque) and recited in a style different from that of his companion. When we had finished the prayer, we all went to Allah's Messenger ( صلی اللہ علیہ وسلم ) and said to him: This man recited in a style to which I objected, and the other entered and recited in a style different from that of his companion. The Messenger of Allah ( صلی اللہ علیہ وسلم ) asked them to recite and so they recited, and the Apostle of Allah ( صلی اللہ علیہ وسلم ) expressed approval of their affairs (their modes of recitation). and there occurred In my mind a sort of denial which did not occur even during the Days of Ignorance. When the Messenger of Allah ( صلی اللہ علیہ وسلم ) saw how I was affected (by a wrong idea), he struck my chest, whereupon I broke into sweating and felt as though I were looking at Allah with fear. He (the Holy Prophet) said to me: Ubayy. a message was sent to me to recite the Qur'an in one dialect, and I replied: Make (things) easy for my people. It was conveyed to me for the second time that it should be recited in two dialects. I again replied to him: Make affairs easy for my people. It was again conveyed to me for the third time to recite in seven dialects And (I was further told): You have got a seeking for every reply that I sent you, which you should seek from Me. I said: O Allah! forgive my people, forgive my people, and I have deferred the third one for the day on which the entire creation will turn to me, including even Ibrahim (peace be upon him) (for intercession).

Ubayy bin Ka'b reported that he was sitting in a mosque that a person entered it and he observed prayer, and made recitation, the rest of the hadith is the same.

Ubayy bin Ka'b reported that the Apostle of Allah ( صلی اللہ علیہ وسلم ) was near the tank of Banu Ghifar that Gabriel (ؑ) came to him and said: Allah has commanded you to recite to your people the Qur'an in one dialect. Upon this he said: I ask from Allah pardon and forgiveness. My people are not capable of doing it. He then came for the second time and said: Allah has commanded you that you should recite the Qur'an to your people in two dialects. Upon this he (the Holy prophet) again said: I seek pardon and forgiveness from Allah, my people would not be able to do so. He (Gabriel (ؑ)) came for the third time and said: Allah has commanded you to recite the Qur'an to your people in three dialects. Upon this he said: I ask pardon and forgiveness from Allah. My people would not be able to do it. He then came to him for the fourth time and said: Allah has commanded you to recite the Qur'an to your people in seven dialects, and in whichever dialect they would recite, they would be right.
