Sayyiduna Bara’ bin Azib (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: Bring me a shoulder blade or a tablet, then he dictated this verse:
“The believers who sit (at home) are not equal...”So the Prophet (peace and blessings be upon him) called Sayyiduna Zayd (may Allah be pleased with him), who brought a shoulder blade, and he wrote this verse on it. When Sayyiduna Ibn Umm Maktum complained about his disability, these words were revealed:“Except those who are disabled.”
«ذِكْرُ الْخَبَرِ الْمُدْحِضِ قَوْلَ مَنْ زَعَمَ أَنَّ أَبا إسحق السَّبِيعِيُّ لَمْ يَسْمَعُ هَذَا الْخَبَرَ مِنَ الْبَرَاءِ» Mention of that narration which refutes the stance of the person who claims that Abu Ishaq Sabi’i did not hear this narration from Sayyiduna Bara’ bin Azib (may Allah be pleased with him).
