We would like to point out from the very beginning that this is a very minor issue. The position of hands in Prayer is definitely not one of the integrals of Prayer, for, according to all scholars, salah is deemed as valid regardless of whether one places the hands above or below the navel or on the chest.
there are different opinions regarding this issue. A Muslim must choose what helps him/her maintain humbleness and concentration in Prayer.
In this regard, Sheikh Ahmad Kutty, a senior lecturer and Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states: There is no need to be rigid about this issue, for it is perfectly acceptable to place our hands either below the navel as the Hanafi School teaches, or above the navel as taught by the Shafi`i School. It is also fine, as some hold, to place the hands on the chest, or even to drop them to the side, as is held by some scholars of the Maliki School.
It is highly important for us to know that the differences among various schools of jurisprudence on this issue are not due to the whimsical rulings or improvisations of the imams or the founders of the various schools themselves; rather they are primarily due to the way they have learned the precise practice and precedents of the Prophet (peace and blessings be upon him) through his own Companions. In other words, these differences are coming from the Companions of the Prophet (peace and blessings be upon him) whose legacy the imams transmitted to their disciples.
In conclusion, it is perfectly acceptable for us to follow the opinion that suits us more.
