It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "The gate of my Ummah through which they will enter Paradise is as wide as the distance covered by an excellent, swift rider (he (peace and blessings be upon him) repeated the words 'swift rider' three times), and despite that they will be so crowded and pressed at that gate that their shoulders will almost be dislodged."
