Sahih al-Bukhari 4524, 4525
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.'
حَدَّثَنَا إِبْرَاهِيمُ بْنُ مُوسَى، أَخْبَرَنَا هِشَامٌ، عَنِ ابْنِ جُرَيْجٍ، قَالَ سَمِعْتُ ابْنَ أَبِي مُلَيْكَةَ، يَقُولُ قَالَ ابْنُ عَبَّاسٍ ـ رضى الله عنهما ـ ‏{‏حَتَّى إِذَا اسْتَيْأَسَ الرُّسُلُ وَظَنُّوا أَنَّهُمْ قَدْ كُذِبُوا‏}‏ خَفِيفَةً، ذَهَبَ بِهَا هُنَاكَ، وَتَلاَ ‏{‏حَتَّى يَقُولَ الرَّسُولُ وَالَّذِينَ آمَنُوا مَعَهُ مَتَى نَصْرُ اللَّهِ أَلاَ إِنَّ نَصْرَ اللَّهِ قَرِيبٌ‏}‏      فَلَقِيتُ عُرْوَةَ بْنَ الزُّبَيْرِ فَذَكَرْتُ لَهُ ذَلِكَ فَقَالَ قَالَتْ عَائِشَةُ مَعَاذَ اللَّهِ، وَاللَّهِ مَا وَعَدَ اللَّهُ رَسُولَهُ مِنْ شَىْءٍ قَطُّ إِلاَّ عَلِمَ أَنَّهُ كَائِنٌ قَبْلَ أَنْ يَمُوتَ، وَلَكِنْ لَمْ يَزَلِ الْبَلاَءُ بِالرُّسُلِ حَتَّى خَافُوا أَنْ يَكُونَ مَنْ مَعَهُمْ يُكَذِّبُونَهُمْ، فَكَانَتْ تَقْرَؤُهَا ‏{‏وَظَنُّوا أَنَّهُمْ قَدْ كُذِّبُوا‏}‏ مُثَقَّلَةً‏.‏
