Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrated that the Messenger of Allah (peace and blessings be upon him) said: "My Ummah has been given, at the time of calamity, something that was not given to any other nation: Inna lillahi wa inna ilayhi raji'un (We belong to Allah and to Him we return) [Surah al-Baqarah: 156]."
