Aslam

Praise be to Allah.It is mustahabb to kiss the hands of righteous people

and the greatest scholars, and it is makrooh to kiss the hand of anyone else. The hand of

the beardless man should not be kissed under any circumstances,

(From Fatawa al-Imaam al-Nawawi, p. 71)

In the commentary on the book, it says:

If a person wants to kiss another person's hand, if this is because of

his asceticism, righteousness, knowledge, position or modesty, or other reason that has to

do with his commitment to religion, then it is not makrooh. In such cases it is mustahabb,

because Abu Ubaydah kissed the hand of Umar (may Allaah be pleased with them

both).

But if it is because of the persons riches, wealth, high rank or

status in the eyes of the people of this world, and so on, then it is intensely makrooh.

Al-Mutawalli, one of our companions, said: It is not permitted, and he

indicated that it is haraam.

It was narrated in Sunan Abi Dawood that Zaari (may Allaah

be pleased with him), who was among the delegation of Abd Qays, said: We

started to get out from our howdahs and we kissed the hands and feet of the Prophet

(peace and blessings of Allaah be upon him).
