10. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ‘Uthman ibn ‘Isa from ibn Muskan from abu Basir who has said the following: “I once asked him (the Imam) عليه السلام, about a man who during a journey had a certain amount of water but forgot all about it, and with Tayammum performed Salah (prayer). Then he remembered that there was water with him and still there is time for Salah (prayer). He (the Imam) said, ‘He must take Wudu’ and perform Salah (prayer) again.’ I (the narrator) then asked him (the Imam) if Tayammum for one experiencing Hayd (menses) and sexual relation who cannot find water is the same. He (the Imam) said, ‘Yes, it is the same.’”
