This means saying " I will perform tayamum kurbat LiLLaHi tala or you say I am performing tayamum instead of kurbati mina Allah tala." Strike both palms on soil or any valid medium for tayammum. Place both hands - palms inwards - on your forehead and pass them down to your eyebrows and then to the tip of the nose. Pass your left palm over the back of your right hand from wrist to fingertips, then do the same with your right palm over the back of your left hand.
Conditions regarding Performance of Tayyamum All parts stated in the rules must be wiped else tayamum will not be valid. The forehead and backs of hands should be taahir. Incase any of the parts used in tayyamum i.e. forehead, backs or palms of the hand are tied with a bandage or plaster that cannot be removed, then tayyamum is allowed with this. Whoever is performing tayamum while on duty without knowing when he will leave, He can perform tayamum and say his prayer.
3.The usage of water is harmful to ones health, e.g. it can cause sickness. However, if there is an alternative such as warm water, then one should perform wudhoo with it. 4.Water is available, but it belongs to someone else, and one cannot obtain his permission. The solution here is to perform tayammum. 5.Water is available, but the time is short i.e. if you perform wudhoo or Ghusl, part of or your entire prayer will be Qadha then you have to perform tayammum.
Conditions regarding Replacing of Wudhoo with Tayyamum It is not necessary to be very sure that water is harmful to oneself but by guessing that the water may be harmful, one can perform tayammum. In regards to time, if you can perform wudhoo and pray without the mustahabat e.g. Qunut in the period of time available, then you must do this and tayyamum is not allowed.
Things that can be used for Tayamum Tayammum can be performed with clean dust, soil, sand, limestone, dry mud, clay or marble (semi-precious stone).Incase the soil, sand, stone, and the lump of earth are not available, we must perform tayammum with clay.
