Someone did not fast a day in Ramadan and made up for it on a Friday

Q 1: Someone did not fast a day in Ramadan and then made up for it on 20th of Shawwal. However, this day coincided with a Friday. Many people said that it is impermissible to devote Friday to fasting. Do I have to repeat this fast?

A: It is established in the Prophetic Sunnah (acts, sayings, or approvals of the Prophet) that it is prohibited to single out Friday for a voluntary fast unless one fasts a day before or after it or if it coincides with a day that someone usually fasts. This is based on the Hadith narrated by Abu Hurayrah (may Allah be pleased with him) who said: The Messenger of Allah (peace be upon him) said: Do not single out the night (preceding) Friday among the nights for prayer and do not single out Friday among the other days for fasting except if it coincides with a day on which you habitually fast. (Reported by Muslim and Al-Nasa'y) The Prophet (peace be upon him) said in an authenticated Hadith: “None of you should fast on Friday unless he fasts a day before it or a day after it.” However, if fasting on this day is not because it is a Friday but with the intention of making up a missed day of fast or because it coincides with the Day of `Arafah (9th of Dhul-Hijjah), then there is nothing wrong with this In Sha’a-Allah (if Allah wills).
