When the Verse:-- "Not equal are those of the believers who sit (at home)" (4.95) was revealed, Allah Apostle called for Zaid who wrote it. In the meantime Ibn Um Maktum came and complained of his blindness, so Allah revealed: "Except those who are disabled (by injury or are blind or lame..." etc.) (4.95)  

لَمَّا نَزَلَتْ {لاَ يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ} دَعَا رَسُولُ اللَّهِ ﷺ زَيْدًا فَكَتَبَهَا فَجَاءَ ابْنُ أُمِّ مَكْتُومٍ فَشَكَا ضَرَارَتَهُ فَأَنْزَلَ اللَّهُ {غَيْرَ أُولِي الضَّرَرِ}  

[Machine] He heard Al-Bara'ah saying about this verse: "The believers who sit at home are not equal to those who strive in the cause of Allah." The Prophet ﷺ commanded Zaid to write it down, so he brought a shoulder blade and wrote it. Then, Ibn Umm Maktum complained to him about his difficult situation, so the verse was revealed: "The believers who sit at home are not equal to those who strive in the cause of Allah except for the disabled." (Quran 4:95)  

أَنَّهُ سَمِعَ الْبَرَاءَ يَقُولُ فِي هَذِهِ الْآيَةِ {لَا يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ} [النساء 95] {وَالْمُجَاهِدُونَ فِي سَبِيلِ اللهِ} [النساء 95] قَالَ فَأَمَرَ رَسُولُ اللهِ ﷺ زَيْدًا فَجَاءَ بِكَتِفٍ فَكَتَبَهَا قَالَ فَشَكَا إِلَيْهِ ابْنُ أُمِّ مَكْتُومٍ ضَرَارَتَهُ فَنَزَلَتْ {لَا يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ غَيْرُ أُولِيالضَّرَرِ} [النساء 95]  

[Machine] "When this verse was revealed, 'Those who stay behind from the believers are not equal to those who strive in the cause of Allah' [Surah An-Nisa, 4: 95] and 'And those who strive in the cause of Allah' [Surah An-Nisa, 4: 95], the Messenger of Allah ﷺ called Zaid and he brought a shoulder blade and wrote it (the verse) down. Then Ibn Umm Maktum came and complained to the Messenger of Allah ﷺ , so the verse 'Except for those who are disabled' [Surah An-Nisa, 4: 95] was revealed."  

لَمَّا نَزَلَتْ هَذِهِ الْآيَةُ {لَا يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ} [النساء 95] {وَالْمُجَاهِدُونَ فِي سَبِيلِ اللهِ} [النساء 95] دَعَا رَسُولُ اللهِ ﷺ زَيْدًا فَجَاءَ بِكَتِفٍ فَكَتَبَهَا قَالَ فَجَاءَ ابْنُ أُمِّ مَكْتُومٍ فَشَكَاضَرَارَتَهُ إِلَى رَسُولِ اللهِ ﷺ فَنَزَلَتْ {غَيْرُ أُولِي الضَّرَرِ } [النساء 95]  

[Machine] When the verse "The believers who stay behind" [Quran 4:95] was revealed, followed by "except for those who are disabled" [Quran 4:95], the Prophet Muhammad ﷺ summoned Zaid and dictated these verses to him. However, Ibn Umm Maktum, who was blind, complained about his own situation. As a result, the verse was revealed again, clarifying that "The believers who stay behind, other than those who are disabled" [Quran 4:95].  

لَمَّا نَزَلَتْ {لَا يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ} [النساء 95] {وَالْمُجَاهِدُونَ فِي سَبِيلِ اللهِ} [النساء 95] دَعَا رَسُولُ اللهِ ﷺ زَيْدًا فَجَاءَ بِكَتِفٍ وَكَتَبَهَا فَشَكَا ابْنُ أُمِّ مَكْتُومٍ ضَرَارَتَهُ فَنَزَلَتْ {لَا يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ غَيْرُ أُولِي الضَّرَرِ} [النساء 95]  

[Machine] I heard Al-Bara'a saying when this verse was revealed {Not equal are those believers remaining [at home] - other than the disabled - and the mujahideen [who strive and fight] in the cause of Allah with their wealth and their lives. Allah has preferred the mujahideen through their wealth and their lives over those who remain [behind], by degrees.} [Quran 4:95], the Messenger of Allah ﷺ called Zaid and he brought a shoulder blade, then the Prophet ﷺ wrote it down. Ibn Umm Maktum, who was blind, complained about its harm, so the verse was revealed {Not equal are those believers remaining [at home] - other than the disabled - and the mujahideen [who strive and fight] in the cause of Allah with their wealth and their lives except for the disabled, Allah has preferred the mujahideen through their wealth and their lives over those who remain [behind].} [Quran 4:95].  

سَمِعْتُ الْبَرَاءَ يَقُولُ لَمَّا نَزَلَتْ هَذِهِ الْآيَةُ {لَا يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ} [النساء 95] دَعَا رَسُولُ اللَّهِ ﷺ زَيْدًا فَجَاءَ بِكَتِفٍ فَكَتَبَهَا وَشَكَا ابْنُ أُمِّ مَكْتُومٍ ضَرَارَتَهُ فَنَزَلَتْ {لَا يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ غَيْرُ أُولِي الضَّرَرِ} [النساء 95]  

[Machine] I heard Al-Bara' saying, when this verse was revealed "Not equal are those believers who sit [at home] and those who strive and fight in the cause of Allah," the Messenger of Allah ﷺ called Zaid and he came with a shoulder on which it was written. Ibn Umm Maktum complained of his disability's harm, so the verse "not [to be incurred] by those who have incurred [the obligation of] the discharge of a burden" was revealed.  

سَمِعْتُ الْبَرَاءَ يَقُولُ لَمَّا نَزَلَتْ هَذِهِ الْآيَةُ {لَا يَسْتَوِي الْقَاعِدُونَ مِنَ الْمُؤْمِنِينَ} دَعَا رَسُولُ اللَّهِ ﷺ زَيْدًا فَجَاءَ بِكَتِفٍ فَكَتَبَهَا فِيهِ فَشَكَا ابْنُ أُمِّ مَكْتُومٍ ضَرَارَتَهُ فَنَزَلَتْ {غَيْرَ أُولِي الضَّرَرِ}
