It is narrated from Hazrat Salim bin Abi Al-Ja'd that he says: It was said to Hazrat Abu Darda (may Allah be pleased with him) that Hazrat Abu Sa'd bin Munabbih has freed one hundred slaves from his wealth. He replied: Beware! Freeing one hundred slaves from a single person's wealth is a great thing, but shall I not tell you something even better than that? Remain attached to faith day and night, and let your tongue remain constantly engaged in the remembrance of Allah.
