Nein ist er nicht
Von welchen Manuskripten sprichst du? Damit du es weißt scribal errors sind menschlich und sie beeinträchtigen nicht den Erhalt des Qurans
Und die Ahruf und die Qira’at sind auch kein Rätsel
Sie sind eindeutig in unseren Quellen bewiesen
Narrated Ibn `Abbas:
Allah's Messenger (ﷺ) said, "Gabriel read the Qur'an to me in one way (i.e. dialect) and I continued asking him to read it in different ways till he read it in seven different ways."
Narrated `Umar bin Al-Khattab:
I heard Hisham bin Hakim reciting Surat Al-Furqan during the lifetime of Allah's Messenger (ﷺ) and I listened to his recitation and noticed that he recited in several different ways which Allah's Messenger (ﷺ) had not taught me. I was about to jump over him during his prayer, but I controlled my temper, and when he had completed his prayer, I put his upper garment around his neck and seized him by it and said, "Who taught you this Sura which I heard you reciting?" He replied, "Allah's Messenger (ﷺ) taught it to me." I said, "You have told a lie, for Allah's Messenger (ﷺ) has taught it to me in a different way from yours." So I dragged him to Allah's Messenger (ﷺ) and said (to Allah's Messenger (ﷺ)), "I heard this person reciting Surat Al-Furqan in a way which you haven't taught me!" On that Allah's Apostle said, "Release him, (O `Umar!) Recite, O Hisham!" Then he recited in the same way as I heard him reciting. Then Allah's Messenger (ﷺ) said, "It was revealed in this way," and added, "Recite, O `Umar!" I recited it as he had taught me. Allah's Messenger (ﷺ) then said, "It was revealed in this way. This Qur'an has been revealed to be recited in seven different ways, so recite of it whichever (way) is easier for you (or read as much of it as may be easy for you).
Ubayy b. Ka'b said:
The Prophet (ﷺ) was present at the pool of Banu Ghifar, Gabriel came to him and said: "Allah has commanded you to make your community read (the Qur'an) in one harf. He (the Prophet) said: 'I beg Allah His pardon and forgiveness; my community has not strength to do so'. He then came for the second time and told him the same thing till he reached up to seven harfs. Finally, he said: 'Allah has commanded you to make your community read (the Qur'an) in seven harfs; in whichever mode they read, that will be correct.
Das war nur ein winziger Bruchteil der vielen Belege Es gibt im Islam keinen Zweifel dass es Ahruf und Qira’at gibt und sie auch von Allah (s.w.t.) sind
