Narrated Ibn Abu Mulaika:
Ibn 'Abbas recited: "(Respite will be granted) until when the Apostles gave up hope (of their people) and thought that they were denied (by their people). There came to them Our Help ...." (12.110) reading Kudhibu without doubling the sound 'dh', and that was what he understood of the Verse. Then he went on reciting: "..even the Apostle and those who believed along with him said: When (will come) Allah's Help? Yes, verily, Allah's Help is near." (2.214)
Then I met 'Urwa bin Az-Zubair and I mentioned that to him. He said, "Aisha said, 'Allah forbid! By Allah, Allah never promised His Apostle anything but he knew that it would certainly happen before he died. But trials were continuously presented before the Apostles till they were afraid that their followers would accuse them of telling lies. So I used to recite:--
"Till they (come to) think that they were treated as liars." reading 'Kudh-dhibu with double 'dh.'
