The lives and works of the four imams who founded the four great canonical schools of thoughts of Islamic fiqh.
Islamic Guidance
Imam Malik
The majority of scholars view that it is not permissible for Muslim men and women to shake hands if they are not related to each other. The other view permits shaking hands with elderly women if there is no temptation.
Imam Ash-Shafi'i
In some greeting situations people bow to each other by lowering their heads or chests. But Muslims are not permitted to bow to each other or to non-Muslims. As it is a greeting of worship that is only offered to God.
