It is recognized from several cabbalas that holy Prophet (s.a.) had prostrated on the ground, not on carpet, cloth and like them.
We read in a Hadith from Abu Harira that: “I saw prophet of Allah (s.a.) in a rainy day prostrating on the ground and its effects were showing on his forehead and nose”.1
If prostration of carpet and cloth was allowed, then it was not necessary that his holiness prostrate on the ground.
Also Ayesha says: “I had never seen that prophet of Allah (s.a.) cover his forehead (during prostration) with anything”.2
Ibn Hajr says in explanation of this Hadith: This Hadith refers to the principle that during prostration forehead should reach the ground, but it is not obligatory when person is ill or incapable of that”.3
It has been mentioned in another cabbala from Maymuna (another wife of prophet of Allah) that: Prophet (s.a.) had performed prayer and prostrated on a piece of sennit mat”.1
It is obvious that the meaning of this Hadith is that Prophet had prostrated on his sennit Sajjada (a mat for performing prayer on it, mostly it had been made from palm leaves).
There are several cabbalas in resources of Ahl -e- Sonnat that Prophet had performed prayer on “Khumrah”. (Khumrah is a small mat or Sajjada that is made from palm leaves).
It is wonderful that if Shiites act like this and put a sennit Sajjada under their feet during prayer, they will be accused by some fanatics to heresy and will be looked enraged, while these Ahadith tell that it was tradition of prophet of Allah (s.a.).
And how painful is when traditions considered as heresy!
I will never forget that in one of pilgrimages of Ka’ba when I wanted to perform prayer on a small sennit Sajjada in Prophet’s mosque, one of Wahhabi scholars came to me, take that mat and furiously threw that away, maybe he considered “tradition” as “heresy”!
