Hadith 1248 Reported Mujibah Al-Bahiliyah on the authority of her father or uncle that he visited the Messenger of Allah
once and then went to see him again after a year. His appearance had totally changed. He asked the Messenger of Allah
if he had recognized him. The Messenger of Allah
asked,
"Who are you?'' He replied: "I am Al-Bahili who visited you last year.'' The Messenger of Allah
said,
"You were quite handsome, what has changed your appearance so much?'' He replied, "Since my departure from here, I have not eaten anything except at night.'' The Messenger of Allah
remarked,
"You have put yourself to torture. Observe Saum (fasting) during the Month of Patience (i.e., Ramadan) and fast one day from each month.'' He submitted, "Permit me to observe more voluntary fasts because I have capacity to do so.'' The Messenger of Allah
said,
"Then observe fasts for two days in every month.'' He said, "Permit me to observe more.'' The Messenger of Allah
said,
"Observe fasts on three days in every month.'' He requested that he should be allowed to observe more fasts. The Messenger of Allah
said,
"Fast three days during the sacred months and omit fasting for three days alternately.'' He
joined his three fingers together and left them apart while repeating this sentence thrice. [Abu Dawud].
Commentary: The name of Mujibah Bahiliyah's father was Abdullah bin Harith Al-Bahli, and if this incident relates to his uncle, his name is not well-known. In any case, he used to take meal at night only, that is, he used to observe Saum daily. Because of this routine, his health was greatly affected and the Prophet
prohibited him from observing Saum daily and stressed that he should keep Saum thrice a month only, especially in the sacred months. With the formula of ten-fold reward, he could thus get reward of thirty days Saum in a month. This is how he would be reckoned as one who observes Saum throughout the year. People with weak health should not observe more than three Saum in a month. Those who are healthy, are allowed to observe more Saum, but it will be well if they do so in the style of Prophet Dawud, that is, on alternate days.
