Full Sharh — Riyad as-Salihin 220

English Translation

'Ali bin Abu Talib (May Allah be pleased with him) reported:: I heard the Messenger of Allah (ﷺ) saying, "When a Muslim visits a sick Muslim at dawn, seventy thousand angels keep on praying for him till dusk. If he visits him in the evening, seventy thousand angels keep on praying for him till the morning; and he will have (his share of) reaped fruits in Jannah.".
