Mahmud bin Rabi reported,

Itban bin Malik, who was among the companions of the Messenger of Allah ﷺ from the Ansar and had witnessed Badr, came to the Messenger of Allah ﷺ and said, "Messenger of Allah, my eyesight has weakened, and I lead my people in prayer. When the rains come, the valley between me and them floods, and I cannot reach their mosque to lead them in prayer. I would love it, Messenger of Allah, if you would come and pray in my house, so I could take that spot as a place of prayer."The Messenger of Allah ﷺ said to him, "I will do so, Allah willing."Itban said, the Messenger of Allah ﷺ and Abu Bakr came the next morning after the day had grown bright. The Messenger of Allah ﷺ asked permission to enter, and I granted it. He did not sit down until he had entered the house, then he said, "Where in your house would you like me to pray?"I pointed to a corner of the house, and the Messenger of Allah ﷺ stood and said the takbir. We stood and formed a row behind him, and he prayed two rakahs, then gave the salam. We had detained him for a dish of khazirah we had prepared for him.Some men from the people of the neighborhood, a fair number of them, gathered at the house.

Sahih

عن محمود بن الربيع الأنصاري

أن عتبان بن مالك وهو من أصحاب رسول الله ﷺ ممن شهد بدرا من الأنصار أنه أتى رسول الله ﷺ فقال: يا رسول الله قد أنكرت بصري وأنا أصلي بقومي، فإذا كانت الأمطار سال الوادي الذي بيني وبينهم لم أستطع أن آتي مسجدهم فأصلي بهم، ووددت يا رسول الله أنك تأتيني فتصلي في بيتي فأتخذه مصلى، قال فقال له رسول الله ﷺ: سأفعل إن شاء الله، قال عتبان: فغدا رسول الله ﷺ وأبو بكر حين ارتفع النهار فاستأذن رسول الله ﷺ فأذنت له، فلم يجلس حتى دخل البيت ثم قال: أين تحب أن أصلي من بيتك؟ قال فأشرت له إلى ناحية من البيت، فقام رسول الله ﷺ فكبر، فقمنا فصفنا فصلى ركعتين ثم سلم، قال وحبسناه على خزيرة صنعناها له. قال فثاب في البيت رجال من أهل الدار ذوو عدد فاجتمعوا.
