Musnad Abi Ya'la 6067 — The Messenger of Allah ﷺ, passing by al-Baqi'

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that "The Messenger of Allah (peace and blessings be upon him), passing by al-Baqi', came near a woman who had collapsed over a grave, weeping. He (peace and blessings be upon him) said to her: 'O servant of Allah, fear Allah and be patient.' The woman (not recognising him (peace and blessings be upon him)) said: 'O servant of Allah, I am a grief-stricken woman whose child has been taken from her.' He (peace and blessings be upon him) said again: 'O servant of Allah, fear Allah and be patient.' She said: 'O servant of Allah, if this calamity had befallen you, you would have excused me.' He (peace and blessings be upon him) said once more: 'O servant of Allah, fear Allah and be patient.' She said: 'O servant of Allah, you have said what you had to say, now go away from me.' The narrator said: When the Messenger of Allah (peace and blessings be upon him) had gone away from there, a man from among his (peace and blessings be upon him) Companions came to the woman and asked: 'What did that man who was leaving say to you?' She said: 'He said such and such to me.' He asked: 'Do you know him?' She said: 'No.' He told her: 'That was the Messenger of Allah (peace and blessings be upon him).' The narrator said: The woman (on hearing this) got up at once, distressed, and began to say: 'O Messenger of Allah (peace and blessings be upon him), I will be patient, I will be patient.' Then the Messenger of Allah (peace and blessings be upon him) said: 'True patience is at the first shock (the first blow) of the calamity; true patience is at the first shock of the calamity.'"
