Al-Matalib al-'Aliyah 786 — The reward of one whose child dies

It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that she said: "Whoever has three children die in his lifetime, and he is patient over this calamity and seeks reward from Allah Almighty alone, those children will, by the command and permission of Allah Almighty, become a screen and barrier for that person from the fire of Hell."
This report is mawquf (stopping at the Companion), and its chain is of hasan (good) grade.
