When beginning to worship, saying orally only is not called niyyat. Worships done without the niyyat made by heart are not acceptable in the four Madhhabs. No one heard Rasulullah, the Sahaba , the Tabi’in, or even the four imams, make niyyat by tongue. Hadrat Imam-i Rabbani (rahmatullahi ’alaih) says in the hundred and eighty-sixth letter of Maktubat, “Niyyat is made by heart. It is bid’at  to make niyyat orally. This bid’at has been called hasana (good, useful). But this bid’at annihilates not only the sunnat  but also the fard. For, many people have been making niyyat only by tongue, without passing the niyyat through their heart. Thus niyyat through heart, one of the fards (principles) of namaz, has been neglected, and namaz has been nullified. This faqir (hadrat Imam-i Rabbani means himself) do not recognize any bid’at as ‘Hasana’. I see no beauty in any bid’at.” It is sunnat to make niyyat orally in Shafi’i and in Hanbali Madhhabs. It is stated in Ibni Abidin, “That it is fard to make niyyat when beginning namaz has been stated unanimously. Niyyat is made only with the heart. It is bid’at to make it only in words. It is permissible for a person who makes niyyat with his heart to make niyyat verbally also in order to be safe against doubts.
 namaz: prayer that is performed five times per day in Islam.
 qibla: direction towards the Ka’ba. The direction turned towards during worshipping (in Islam, toward the Ka’ba).
 madhhab: all of what a profound ‘alim of (especially) Fiqh (usually one of the four-Hanafi, Shafi’i, Maliki, Hanbali) or iman (one of the two, namely Ash-ari, Maturidi) communicated.
 Sahaba: if a Muslim has seen the Prophet, or talked to him, at least once when the Prophet was alive, he is called Sahabi. Plural form of Sahabi is Sahaba or As’hab. The word Sahaba-i kiram includes all those great people each of whom has seen the Prophet at least once. The lowest of the Sahaba is much higher than the highest of other Muslims. If a person has not seen the Prophet but has seen or talked to one of the Sahaba at least once, he is called Tabi’. Its plural form is Tabi’in. In other words, the Tabi’in are the successors of the Sahaba. If a person has not seen any of the Sahaba but has seen at least one of the Tabi’in, he is called Taba’i Tabi’in. The Sahaba, the Tabi’in and the Taba’i tabi’in altogether are called the Salaf-i salihin (the early savants).
 bid’at: (pl. bida’) heresy; false, disliked belief or practice that did not exist in the four sources of Islam but which has been introduced later as an Islamic belief or ‘ibada in expectation of thawab (blessings) ; heresy.
 Sunnat: 1- (when used alone) The Shari’at; 2- (when used together with the name Book) The hadith of the Prophet. 3- (when used together with the word Fard) Any action, word or thought liked and commanded by the Prophet.
