Rules of Prostration 12item What is ‘the ruling on placing toes on the ground in addition to the big toe while doing prostration? What is the best dhikr to recite after the obligatory dhikrs of prostration and rukū‘? Recently a turbah for prayers has been manufactured that it counts the rak‘ahs and prostrations for the person praying and it removes doubt to some degree. Please clear the matter for us with your opinion, considering that when the forehead is placed on it, it moves down a little due to the presence of a metal spring beneath it. Is it correct to do prostration on it? In prayer, is it incorrect to place one’s hands on perforated floor tiles? What is one’s shar‘ī duty upon listening to a verse that requires prostration when the reciter is not present, as from a radio, TV or recording instrument? Is there any problem in using, for prostration, a turbah blackened and dirty in such a way that the stain covering it obstructs the forehead from touching the turbah? While performing prostration it is obligatory to place the seven body parts of prostration on the ground. But we are not able to do this due to our particular physical problem (as disabled veterans who use wheelchairs). So for the purpose of prayer we either raise the turbah to our forehead or place the turbah on the arm of our chair and perform prostration on it. Is this practice correct? If a woman does prostration on a turbah while her forehead (the place of prostration in particular) is covered by her ḥijāb; is it obligatory for her to repeat this prayer? What is the ruling on performing prostration and tayammum on cement or concrete tiles? Which foot should we place upon the other while sitting down after prostration? A woman after putting her head on the turbah realizes that her forehead is not in complete contact with it due to her scarf or the like. So she raises her head and places it again after having removed the hindrance. What is the ruling on this issue? Moreover, if this last action of hers is counted as a separate prostration, then what becomes of the prayers that she has done (in this manner)? What is the rule of performing prostration on marble (with which the yard of some sacred shrines is paved)?
