It was narrated that Anas bin Malik said: “When the Prophet (ﷺ) died, there was a man in Al-Madinah who used to make a niche in the grave and another who used to dig graves without a niche. They said: ‘Let us pray Istikharah to our Lord and call for them both, and whichever of them comes first, we will let him do it.’ So they were both sent for, and the one who used to make the niche-grave came first, so they made a niche-grave for the Prophet (ﷺ).”

It was narrated that ‘Aishah said: “When the Messenger of Allah (ﷺ) died, they differed as to whether his grave should have a niche or a ditch in the ground, until they spoke and raised their voices concerning that. Then ‘Umar said: ‘Do not shout in the presence of the Messenger of Allah (ﷺ), living or dead,’ or words to that effect. So they sent for both the one who made a niche and the one who dug graves without a niche, and the one who used to make a niche came and dug a grave with a niche for the Messenger of Allah (ﷺ), then he (ﷺ) was buried.”
