All acts of worship depends on correct aqidah
Question:
There is (one) here who is lax concerning the importance of aqidah (creed) and he is of the opinion that iman (faith) is sufficient (for him). Do you have any clarification concerning the importance of aqidah for the Muslim and how it reflects on his life, on his relationship with the (Muslim) society (as a whole) and with the non-Muslims?
Answer:
In the name of Allaah, the Most Merciful, the Bestower of Mercy. All praise is due to Allaah, the Lord of the all that exists. And may the peace and blessings be upon our Messenger Muhammad and upon his family and his companions. To proceed:
The correctness of aqidah is the (most) fundamental principle. This is because bearing witness that Laa Ilaaha Illa Allaah Wa Anna Muhammaddan Rasool Allaah (there is no deity worthy of worship except Allaah and that Muhammad is His Messenger), is the first pillar of Islam. And the Messengers called firstly, to the correction of the aqidah because all acts of worship and behavior depends on it and without the correct aqidah, there is no benefit from (these) deeds. The Most High said: “But if they had joined in worship others with Allaah, all that they used to do would have been of no benefit to them.” (Al-An’am (6):88) and their deeds became invalid.
And Allaah said: “Verily, whosoever sets up partners in worship with Allaah, then Allaah has forbidden Paradise for him, and the Fire will be his abode. And for the Dhaalimoon (polytheists and wrong-doers) there are no helpers.” (Al-Maa’idah (5):72)
And the Most High said: “And indeed it has been revealed to you (O Muhammad (peace and blessings be upon him)), as it was to those (Allaah’s Messengers) before you: ‘If you join others in worship with Allaah, (then) surely (all) your deeds will be in vain, and you will certainly be among the losers.’” (Az-Zumar (39):65)
From these texts and other than them, it is clear that the correction of the aqidah is from the important (affairs) and at the forefront of the da’wah. And the first (affair) to establish for the da’wah is the correction of aqidah. And the Prophet (peace and blessings be upon him) remained in Makkah for thirteen years after his mission began, calling the people to the correction of the aqidah and to at-Tawhid. And the fara’id (obligatory acts of worship) were not revealed to him except in Madinah.
Yes, and the salat (prayer) was made obligatory upon him in Makkah before the hijrah and the rest of the shar’iah was imposed on him after the hijrah. From this we have evidence that deeds are not accepted except after the correction of the aqidah.
And this is for the one who says: That the iman is sufficient without having interest for the aqidah. This is contradictory because iman is not iman except if the aqidah is correct. And if the aqidah is not correct, then there is no iman, and (there is) no deen (religion).
