Mary - 19:48
I am leaving you and those whom you call upon besides Allah, I call upon my Lord, and I hope that I will not be unfortunate in calling upon my Lord.
The misfortune of those who call upon others besides Allah is that all their good deeds are in vain because of their associating partners, and therefore they deserve the torment:
Prophet Jonah/10:106
Do not call upon those who cannot benefit or harm you except Allah. If you do so, then you will be of the wrongdoers.
Luqman/31:13
"When Lokman advised his son, he said: "My dear son, do not associate partners with Allah; surely shirk (associating partners with God) is a great wrong."
The Companies/39:65
It has been revealed to you and those before you that if you associate partners, all that you do will be in vain and you will be of the losers.
