Silsilah as-Sahihah 3175 — Virtues of the Prophet: He will be first

It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "I was weighed against one thousand individuals from my Ummah, and I was heavier (and their side of the scale was raised so high that) they began to fall upon me from it."
