for other than Allah
Fifth question from Fatwa No. 4042
Q5: What is the ruling on people who vow to sacrifice for anyone other than Allah, namely, for the dead. Yet, at the same time, they say, for instance, "O Lord! if my son or my daughter succeeds, I will sacrifice a sheep for you, O shaykh so and so"?
A: Making vows to anyone other than Allah is an act of Shirk (associating others in worship with Allah). Likewise, offering sacrifices to anyone other than Allah is also an act of Shirk. Allah (Glorified be He) says:
( Part No : 1, Page No:184)
Surah Al-Baqarah, 2: 270 And whatever you spend for spendings (e.g., in Sadaqah - charity for Allâh’s Cause) or whatever vow you make, be sure Allâh knows it all. He also says:Surah Al-An`am, 6: 162 Say (O Muhammad صلى الله عليه وسلم): "Verily, my Salât (prayer), my sacrifice, my living, and my dying are for Allâh, the Lord of the ‘Alamîn (mankind, jinn and all that exists). Surah Al-An`am, 6: 163 He has no partner. The Prophet (peace be upon him) said: Allah curses the one who sacrifices to other than Allah… Making vows is included in Allah's saying:Surah Al-An`am, 6: 162 my sacrifice
May Allah grant us success! May peace and blessings be upon our Prophet Muhammad, his family, and Companions!
