It is narrated from Sayyiduna Ibn Umm Maktum (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) turned towards the people during the Isha prayer and said: "I had resolved to go to those who stay away from this prayer and set their houses on fire over them." So Sayyiduna Ibn Umm Maktum stood up and said: "O Messenger of Allah! You know my condition: I am blind and I have no one to guide me." He (peace and blessings be upon him) asked: "Do you hear the iqamah?" He said: "Yes." He (peace and blessings be upon him) said: "Then attend it." He said (again): "O Messenger of Allah! Between me and the mosque there are date palms and bushes, and I have no regular guide." He (peace and blessings be upon him) asked (again): "Do you hear the iqamah?" He said: "Yes." He (peace and blessings be upon him) said: "Then attend it." And he (peace and blessings be upon him) did not grant him an exemption (to pray at home).
