What is meant by
al-Tawhid al-Talaby al-Irady is that a servant singles out Allah (Exalted be He) for acts of worship such as Salah (Prayer), Sawm (Fast), sacrifice, vows, supplication and other acts of worship. This type of Tawhid is known as Tawhid of worship, acting upon the Saying of Allah (Exalted be He), (Part No. 1; Page No. 20)
Worship Allâh and join none with Him (in worship)
Allah (Glorified be He) also says,
And they were commanded not, but that they should worship Allâh, and worship none but Him Alone (abstaining from ascribing partners to Him)
This is the meaning of the word of Tawhid "La Ilaha illa Allah (there is no god but Allah)." That is why the word Tawhid was denied by the Mushriks of Arabia when the Prophet (peace be upon him) asked them to testify that there is no god but Allah, but they said as mentioned in the Glorious Qur'an,
"Has he made the âlihah (gods) (all) into One Ilâh (God - Allâh). Verily, this is a curious thing!"
The Will of Allah (Exalted be He) is one of His Attributes that are proper for Him. Divine Will is of two types:A: A cosmetic will: It is like Allah's Will to create the heavens and the earth, supply provision for all creatures and fix life spans for them. This is because Allah (Exalted be He) does what He intends and wills. Whatever He intends and wills, must happen. Allah (Glorified be He) says,
Verily, your Lord is the Doer of whatsoever He intends (or wills).
B: A Shari`ah-based will: It is Allah's Will with regard to His servants that they worship Him Alone and join no one with Him in worship. A servant may realize the purpose of His Will. Also, he may be unable to realize the purpose of His Will according to wisdom fixed by Allah (Glorified be He) as referred to in the Saying of Allah (Exalted be He),
Allâh wishes to make clear (what is lawful and what is unlawful) to you, and to show you the ways of those before you, and accept your repentance, and Allâh is All-Knower, All-Wise.
