Narrated Abu Juhaim (RA) :  "Allah's Messenger (SAWS) said, 'If the person who passes in front of another person in Salat knew the magnitude of his sin, he would prefer to wait for 40 (days, monts or years) rather than to pass in front of him". (Abu An-Nadr) said, "I do not remember exactly whether he said 40 days, months or years". (1:489-O.B.)
