The Almighty Allah states in the Holy Quran:
Man zal lazi yashfa’u indahoo illa bi izni.
“Who is it that can intercede with Him, except with His permission.” (Sura Baqara: Verse 225)
From this Quranic injunction, an important fact is becoming apparent to us. Almighty Allah is quite clearly stating to us that not everyone will be given permission to intercede except those to whom He has given permission. It is also a warning to the Idol worshippers, in that they should not believe and hold high esteem of their Idols considering that their Idols have never been given permission to intercede for their worshippers. This clearly proves that their Idols are totally useless.
The beloved slaves of Allah, on the other hand, have been given permission to intercede. The first to intercede will be the Prophet Muhammad (sallal laahu alaihi wasallam) as proven by many authentic sources. Thereafter, the other Prophets, the Martyrs (Shuhada), the Saints, etc. Another important fact we must always bear in mind is that if an individual performs a duty without the Permission of Allah, then this would be considered Shirk, whereas if a duty has been allocated, as will be discussed shortly, then this cannot be considered Shirk.
The Holy Quran is evidence of Hazrat ‘Isa (alaihis salaam) explaining to his nation some of his amazing miracles. This serves as a reminder to all, of the power and authority bestowed by Allah upon His beloved servants. He states:
Wa ubri’ul akmaha wal abrasa wa uh’yil mawta bi iznillahi
“I heal those who are born blind and the leper and I raise
the dead by Allah’s permission.” (Sura Ale Imraan: Verse 49)
We know that to perform amazing duties as explained by Hazrat ‘Isa (alaihis salaam) is indeed the Grace of the Almighty Allah, yet this great Prophet is actually stating that he can perform them. Is he guilty (Allah forbid!) of committing Shirk? No, for he has clearly proven by one verse the difference between Shirk and Tauheed.
When he has said, “these duties are performed through the permission of Allah”, immediately, the question of Shirk is dismissed and the entire concept becomes one of Tauheed. Keeping this in mind, when Muslims state that great Prophets and Saints can perform miracles and do so with the Permission of Allah, how can any sensible person call this action as being Shirk. This belief is purely Tauheed.
If one questions this and states that a Muslim cannot perform these amazing duties (of miracles and interceding) then he is contradicting numerous Quranic verses and Ahadith wherein amazing qualities and attributes of the special servants of Allah are explained.
