Yazid bin Thabit reported,

We went out with the Prophet ﷺ, and when he came to al-Baqi, he saw a fresh grave and asked about it.The people said, "It is so-and-so, the woman."He recognized her and said, "Why did you not inform me about her?"They said, "You were taking your midday rest while fasting, and we did not want to disturb you."He said, "Do not do that. I do not want anyone among you to die while I am among you without your informing me, for my prayer over him is a mercy for him."Then he went to the grave, and we lined up in rows behind him, and he pronounced four takbirs over her.

عن يزيد بن ثابت، وكان أكبر من زيد، قال

خرجنا مع النبي ﷺ فلما ورد البقيع فإذا هو بقبر جديد فسأل عنه فقالوا: فلانة، قال: فعرفها وقال: ألا آذنتموني بها قالوا: كنت قائلا صائما، فكرهنا أن نؤذيك، قال: فلا تفعلوا لا أعرف ما مات منكم ميت ما كنت بين أظهر كم إلا آذنتموني به، فإن صلاتي عليه له رحمة ثم أتى القبر، فصففنا خلفه، فكبر عليه أربعا.
