A man converted to Islam at the age of forty. Should he make up for the missed Salah (prayer)?
A person who converts to Islam does not have to make up for Salah and Sawm (fasting) which they did not perform during the days of their Kufr (disbelief), as Allah stated,
Say to those who have disbelieved, if they cease (from disbelief), their past will be forgiven.
(Surah Al-Anfal, 8: 38). The Prophet (peace be upon him) also stated,
Islam wipes out all that has gone before it (previous misdeeds).
(Part No. 6; Page No. 41) The Prophet (peace be upon him) did not order those who embraced Islam to make up for any missed rites of Islam. The scholars also unanimously agreed upon this.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
