Is there any authentic story regarding a Sahabi, Sa’sa’ah (radiyallahu ‘anhu) that in Jahiliyyah he saved 360 infant girls from being buried alive. When he asked Nabi (salallahu ‘alayhi wasallam) what reward he would get, he was told that being blessed with Iman is your reward.
This is recorded in a lengthy Hadith with a weak chain.
(Al-Mu’jamul Kabir, Hadith: 7412 and Musnad Bazzar; Kashful Astar, Hadith: 72. Also see: Majma’uz Zawaid, vol. 1 pg. 94-95 and Al-Isabah, number: 4068)
Sayyiduna Hakim ibn Hizam (radiyallahu ‘anhu) had also asked Nabi (sallallahu ‘alayhi wasallam) a similar question about the good (charity) that he did prior to Islam. He was given the same answer.
(Sahih Bukhari, Hadith: 2220)
And Allah Ta’ala Knows best,
