It is narrated from Sayyiduna Uqbah bin Amir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "There is no deed of a day and night but a seal is placed upon it. When the believer falls ill, the angels say: 'Rabbana abduka fulan qad habastah' (Our Lord, Your servant so-and-so, You have held him back [through illness]), and Allah, the Mighty and Majestic, says: 'Keep sealing for him according to his (previous, healthy) deeds until he recovers or dies.'"
No one narrated this hadith from Yazid except Ibn Lahi'ah (may Allah have mercy on him).
