The Successor Abu Nadrah (may Allah have mercy on him) said: "I asked Sayyiduna Ibn Abbas (may Allah be pleased with them both) about this saying of Allah, the Mighty and Majestic: 'Not equal are those of the believers who sit (at home), other than those who have a disability.' Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: 'These are people whom pains or illnesses held back; it is they who are "those who have a disability" (uli al-darar, the excused), and the sick person who stays behind is more excused than the healthy person who stays behind.'"
Imam al-Tabarani (may Allah have mercy on him) said: "Only Abu Aqil al-Dawraqi, Bashir bin Uqbah, narrated this hadith from Abu Nadrah."
