Sayyidah Aishah (may Allah be pleased with her) narrates that the Prophet (peace and blessings be upon him) forbade them from continuous fasting (wisal) out of compassion for them. They said: But you (peace and blessings be upon him) also practise wisal. He said: "I am not like you; my Lord gives me food and drink."
