It is narrated from Abu al-Ash'ath al-San'ani (may Allah have mercy on him) that he went to the congregational mosque of Damascus, setting out early at midday, and there he met Sayyiduna Shaddad bin Aws (may Allah be pleased with him), and al-Sunabihi (may Allah have mercy on him) was with him. I asked: "May Allah have mercy on you both, where are you heading?" They replied: "We intend (to go) here to visit a sick brother of ours." So I too went along with them until we reached that man. The two of them asked: "How have you begun your morning?" He said: "I have begun my morning with the blessing of Allah and His favour." Then Sayyiduna Shaddad (may Allah be pleased with him) said: "Receive glad tidings! For I heard the Messenger of Allah (peace and blessings be upon him) say: 'Allah, the Mighty and Majestic, says: When I test one of My believing servants and he endures with patience the trial I have given him and praises Me, then he rises from that bed of his (as pure) from sins as he was on the day his mother gave birth to him. And the Lord, the Mighty and Majestic, says to (the angels appointed as) guardians: Indeed, it is I who confined this servant of Mine and put him to trial, so continue for him the same reward that you used to record for him while he was healthy and well.'"
This hadith is narrated from Sayyiduna Shaddad (may Allah be pleased with him) only with this chain; Isma'il bin Ayyash is alone in narrating it.
