Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: “There are three types of people who are under the protection and guarantee of Allah: the one who goes out towards any mosque of Allah, the one who goes out to strive in the way of Allah, and the one who goes out to perform Hajj.”
