From `Abdul`Aziz ibn `Abdullah ibn Baz to the dignified brother S. Sh. H. N., May Allah grant you success! Assalamu `alaykum warahmatullah wabarakatuh (May Allah's Peace, Mercy, and Blessings be upon you!). I have received your letter and its content is clear. You ask about some youth who say that Allah may not be sought for help by the status of the Prophet (peace be upon him). This is correct because there is no authentic proof that permits seeking Allah's help by the status of anyone, by the rank of someone, or by the soul of anyone. However, it is not an act of polytheism, rather an innovation and one of the means to polytheism according to the majority of scholars. The Prophet (peace be upon him) holds great rank and status in the sight of Allah and in the sight of the believers. There is no sound Islam or Iman (Faith) for anyone except with the testimony of La ilaha illa Allah (there is no deity but Allah) and Muhammad is the Messenger of Allah. However, it is not permissible to draw near to Allah or employ Tawassul (supplicating Allah by the status of someone) except with a statement or action that Allah ordained, as the Prophet's stated: Whoever performs an action that is not in accordance with our Shari'ah, it is to be rejected.
Therfore, it is obligatory on Muslims to glorify the Prophet (peace be upon him) in the manner that Allah has ordained for him, such as following, loving him, glorifying his Sunnah,and calling to it, as well as warning against those who act against it and invoking peace and blessings frequently upon him. Unfortunately, your letter contains some errors such as attributing to Allah the following: (Allah says: the left hand is an organ in the body such as the right hand) which are not the words of Allah. And your saying: (and we have made over all those endowed with knowledge is the AllKnowing (Allah)), which is also not from the words of Allah. The Nass (Islamic text from the Qur'an or the Sunnah ) is: but over all those endowed with knowledge is the AllKnowing (Allâh). So we advise you to be careful and not to speak about Allah without knowledge. May Allah guide your heart and actions!
The left hand is to be used in certain actions different from the right one. Allah legislated that the right hand must be used for shaking hands, eating, taking, giving, etc. As for the left hand, it is used for removing impurity such as after defecation, Ghusl (ceremonial bath), and Istinthar (blowing water out of one's nose during ablution), etc. There is no harm in seeking help with the left hand along with the right one to lift heavy objects, handling things, and lifting them while in Ihram (ceremonial state for Hajj and `Umrah), at bowing, rising from bowing, and when rising from the first Tashahhud. It is also used in bowing and prostration as well known in Shari`ah. May Allah guide you, us, all youth as well as all Muslims to understand His Deen and hold firm to it. May Allah protect us from the misleading turmoil for He is the All Hearer and Near. Assalamu `alaykum warahmatullah wabarakatuh (May Allah's Peace, Mercy, and Blessings be upon you)!
