Musnad Abu Ya'la al-Mawsili 106:72

And with his chain of narration from Abu Ishaq, that he heard al-Bara’ say regarding this verse: "Those of the believers who sit [at home], other than those who have a disability, are not equal to those who strive in the cause of Allah" (An-Nisa). He said: So the Messenger of Allah (ﷺ) commanded Zayd, and he brought a shoulder blade. He said: Then Ibn Umm Maktum complained of his blindness, and there was revealed: "Those of the believers who sit [at home], other than those who have a disability, are not equal to those who strive in the cause of Allah" (An-Nisa).
