Ya’la bin Umayyah (may Allah be pleased with him) says: I asked Sayyiduna ‘Umar bin Khattab (may Allah be pleased with him) that Allah Almighty has said that if you fear that the disbelievers may put you in trial, then there is no sin upon you in shortening the prayer, whereas now people are in peace? Sayyiduna ‘Umar (may Allah be pleased with him) replied to me saying: That which amazed you, also amazed me, but when I asked the Messenger of Allah (peace and blessings be upon him), he (peace and blessings be upon him) said: This is a charity (and concession) which Allah has given to you, so accept His concession.
