Method of making tayammum with a small stone
Q: In Tayammum, is it necessary that the whole palm/hand be able to touch the earth? For example, if someone is sick on a hospital bed, if a small pebble was brought to them, and when they strike this pebble, first with the right hand and then with the left hand, a very small part of the palms touches the pebble... would this taymmum be valid? So actually my questions are:
1. Can the hands strike the "earth" separately (first strike with right and then left), or do both have to strike the earth together?
2. Can tayammum be done with "earth" which is so small that the whole surface area of the palm doesn't cover the "earth".
