What is Makrooh-e-Tahrimi and Makrooh-e-Tanzihi?

Makruh is of two types as  Makrooh-e-Tahrimi and  Makrooh-e-Tanzihi

What is Makrooh-e-Tahrimi ?
Makrooh-e-Tahrimi is an impermissible act in Deen. It's status is close to status of a haraam act. If one carries out a makrooh-e-tahrimi act, one will be sinful. The consequence of continuously carrying out a makrooh-e-tahrimi act could be disastrous.

What is Makrooh-e-Tanzihi ?
"Makrooh Tanzihi" is the opposite of Sunnat-e-Ghair-Muakkadah". The one who avoids it earns goodness and reward and in case of commission he is liable to neither torment nor Divine anger



Conditions for Makrooh-e-Tahrimi in Namaz

1. Rule: To cough without reason or to yawn without reason is Makrooh-e-Tahrimi. If you yawn naturally then there is no harm but you should try and stop it and if you cannot then you should bite your lips and if you still cannot then cover your mouth with your hand, whilst in Qayam use your right hand and in all other position use your left.
2. Rule: To pray Namaz with only your trousers or 'Tehband' on and there is another blanket on top available then it is Makrooh-e-Tahrimi, and if you have no other clothing available then there is no harm.
3. Rule: To delay in the Namaz because you are waiting for someone to join you is Makrooh-e-Tahrimi. If you are delaying it so that they can join the Namaz then it is all right as long as it is no longer than saying 'Subhanallah' twice [Alamgiri].
4. Rule: To pray Namaz with a grave in front and nothing in between is Makrooh-e-Tahrimi [Durr-e-Mukhtar, Alamgiri].

Rule: In Sijdah or Rukooh, to say the Tasbeeh less than three times is Makrooh-e-Tanzihi. If however, you do this because there isn't enough time or you are going to miss the train, then there is no problem.

Rule: To pray Namaz in your working clothes is Makrooh-e-Tanzihi. If however, no other clothes are available then there is no harm.
