Exams, Combining Prayers And Tayammum
I think it would be quite difficult to pray on the train especially with difficulty of doing wudu etc. Thanks!
Quran does not use the word ‘dust’ in those verses ( 4:43 and 5:6 ). The words used are فَتَيَمَّمُوا صَعِيدًا طَيِّبًا — the word ’ صعید ‘ refers to earth’s surface, which means one should refer to any clean earth surface and perform its masah on one’s hands and face. Since clean earth surface would usually contain dust as well, therefore dust becomes a corollary of this directive. On the same basis, ijtihad of doing tayammum on earthly things and things which have some earthly resemblance like walls, tables and other surfaces which collect soil or dust in/on them, sounds appropriate.
