Abu Musa Ashari reported,

I was with the Prophet ﷺ while he was staying at Jiranah, between Mecca and Medina, and Bilal was with him. An Arabi came to the Prophet ﷺ and said, "Will you not fulfill what you promised me?"He replied, "Receive good news."The man said, "You have said 'receive good news' to me too often."The Prophet ﷺ then turned to Abu Musa and Bilal as if angry and said, "He has rejected the good news, so the two of you accept it."They replied, "We accept it."Then he called for a cup of water, washed his hands and face in it, and spat into it. Then he said, "Drink from it, pour some over your faces and chests, and receive good news."They took the cup and did so. Umm Salama then called from behind the curtain, "Leave some for your mother." So they left a portion of it for her.

عن أبي موسى قال

كنت عند النبي ﷺ، وهو نازل بالجعرانة بين مكة والمدينة، ومعه بلال، فأتى النبي ﷺ أعرابي فقال: ألا تنجز لي ما وعدتني، فقال له: أبشر، فقال: قد أكثرت علي من أبشر، فأقبل على أبي موسى وبلال كهيئة الغضبان، فقال: رد البشرى فاقبلا انتما، قالا: قبلنا، ثم دعا بقدح فيه ماء، فغسل يديه ووجهه فيه، ومج فيه، ثم قال: اشربا منه، وأفرغا على وجوهكما ونحوركما وأبشرا، فأخذا القدح، ففعلا، فنادت أم سلمة من وراء الستر: أن أفضلا لأمكما، فأفضلا لها منه طائفة.
