13. Muhammad ibn Yahya has narrated from al-‘Amrakiy al-Naysaburiy from Ali ibn Ja’far from his brother Musa ibn Ja‘far, ‘Alayhim al-Salam, has said the following:

“I once asked him (the Imam) , about a man who performs Sajdah (prostration) on wet growing items. He (the Imam) said, ‘If your forehead touches the ground it is not harmful.’ I asked about stationary grass on the ground and dry leaves while he touches the ground. He (the Imam) said, ‘It is not harmful.’”
