Ibn 'Abbas was asked about this Ayah: Say: "No reward do I ask of you for this except to be kind for my kinship with you (42:23)." So Sa'eed bin Jubair said: 'To be kind to the family of Muhammad.' Ibn 'Abbas replied: 'You know that there was no family of the Quraish except that the Messenger of Allah (ﷺ) had some relatives among them.' He said: 'Except that you should uphold ties of kinship that exist between me and you.'"

← Previous Hadith that the Messenger of Allah (ﷺ) recited: Verily those who say: "Our Lord is Allah, and then they stand firm (41:30)." - He said: "People have said it, then most of them disbelieved, so whoever dies upon it, then he is among those who stood firm."

Jami` at-Tirmidhi Book 47, Hadith 302 Next Hadith → "A Shaikh from Banu Murrah narrated to me, he said: 'I arrived in Al-Kufah and was informed about Bilal bin Abi Burdah so I said: "Indeed there is a lesson in him" so I went to him while he was imprisoned in his home, which he had built.' He said: 'After everything that had happened to him he had changed due to the punishment and the beatings, and now he was living in isolation. So I said: "All praise is due to Allah O Bilal! I have seen you passing you by us holding your nose, and it was not from the dust! And today you are in this state.' So he said: 'Where are you from?' I said: 'From Banu Murrah bin 'Abbad.' So he said: 'Shall I not narrate a Hadith to you, perhaps Allah will benefit you by it?' I said: 'Go ahead.' He said: 'My father, Abu Burdah narrated from his father Abu Musa, that the Messenger of Allah (ﷺ) said: "No worshiper suffers a calamity nor what is worse than that or less, except due to a sin, and what Allah pardons as a result of it is more." He (Abu Musa) said: "And he recited: And whatever misfortune befalls you, it is because of what your hands have earned (42:30)."
