The prohibition of making ghulul in the deen.

 The prohibition of making ghulul in the deen.

Alhamdulillah, ghulul means exaggeration. It is one of the things that leads to shirk.

The Christians made ghulul in praising Jesus a.s taking him to the rank of Allah s.w.t

Allah says in Quran,

An-Nisa' 4:171

يَآأَهۡلَ ٱلۡكِتَٰبِ لَا تَغۡلُواْ فِي دِينِكُمۡ وَلَا تَقُولُواْ عَلَى ٱللَّهِ إِلَّا ٱلۡحَقَّۚ إِنَّمَا ٱلۡمَسِيحُ عِيسَى ٱبۡنُ مَرۡيَمَ رَسُولُ ٱللَّهِ وَكَلِمَتُهُۥٓ أَلۡقَىٰهَآ إِلَىٰ مَرۡيَمَ وَرُوحࣱ مِّنۡهُۖ فَآمِنُواْ بِٱللَّهِ وَرُسُلِهِۦۖ وَلَا تَقُولُواْ ثَلَٰثَةٌۚ ٱنتَهُواْ خَيۡرࣰا لَّكُمۡۚ إِنَّمَا ٱللَّهُ إِلَٰهࣱ وَٰحِدࣱۖ سُبۡحَٰنَهُۥٓ أَن يَكُونَ لَهُۥ وَلَدࣱۘ لَّهُۥ مَا فِي ٱلسَّمَٰوَٰتِ وَمَا فِي ٱلۡأَرۡضِۗ وَكَفَىٰ بِٱللَّهِ وَكِيلࣰا

O People of the Scripture, do not commit excess in your religion[1] or say about Allāh except the truth. The Messiah, Jesus the son of Mary, was but a messenger of Allāh and His word which He directed to Mary and a soul [created at a command] from Him. So believe in Allāh and His messengers. And do not say, "Three"; desist - it is better for you. Indeed, Allāh is but one God. Exalted is He above having a son. To Him belongs whatever is in the heavens and whatever is on the earth. And sufficient is Allāh as Disposer of affairs.

The messenger of Allah pbuh strictly forbade us of praising him to the rank of divinity like how the Christians does to Jesus Christ.

As reported,

Narrated Ibn `Abbas:

The messenger of Allah PBUH said,

Do not claim to be the offspring of other than your fathers, as it is disbelief (unthankfulness) on your part that you claim to be the offspring of other than your real father.' Then Allah's Messenger (ﷺ) said, 'Do not praise me excessively as Jesus, son of Marry was praised, but call me Allah's Slave andHis Apostles.' 

Sahih al-Bukhari 6830.

Praising people to make them equal to Allah takes one out of the Deen And so if we want to praise someone,

What we have to say is,

Narrated Abu Bakra:

A man praised another man in front of the Prophet (ﷺ) . The Prophet (ﷺ) said to him, "Woe to you, you have cut off your companion's neck, you have cut off your companion's neck," repeating it several times and then added, "Whoever amongst you has to praise his brother should say, 'I think that he is so and so and Allah knows exactly the truth, and I do not confirm anybody's good conduct before Allah, but I think him so and so,' if he really knows what he says about him."

Sahih al-Bukhari 2662.
