I say to those who have been put to trial with innovations and whose intentions were (no doubt) good, desiring good when you desire good but we do not know, by Allaah, a path better than the path of the Salaf may Allaah be pleased with them.
My brothers bite onto the Sunnah of the Messenger (sallallaahu alayhi wasallam) with the molars and travel upon the path of the Salaf us-Saalih. Be upon whatever they were upon and then look and see: Will that will injure or hurt you in any way?
I say - and I seek refuge in Allaah that I say something about which I have no knowledge - I say: You will find that many amongst these people who are eager and zealous in innovations are weak and feeble in carrying out those matters whose legislation has been established and whose correctness from the sunnah has also been established. When they finish and depart from these innovations they face the established acts of sunnah with laxity.
All of this is from the evil effects of innovations upon the heart. The evil effects of innovations upon the heart are very great (and severe) and their dangers towards the religion are immense (and significant). Never do a people make an innovation into the religion of Allaah except that they neglect from the Sunnah its like or even greater than it, as some of the people of knowledge from the Salaf have mentioned.
Conversely, when a man feels (and knows) that he is following (and adhering) and not legislating he will obtain, as a result of that, the perfection of awe, submission, humility and worship of the Lord of all the Worlds, and the perfection of following and adherence to the Imaam of the Allaah-fearing, the chief of the messengers and the Messenger of the Lord of all the Worlds, Muhammad (sallallaahu alayhi wasallam)
I direct this advice to all my muslim brothers who consider anything from among the innovations to be good, whether they are related to the Essence of Allaah, His Names and Attributes or to the Messenger of Allaah (sallallaahu alayhi wasallam) and exalting him, that they should fear Allaah and turn away from that. Furthermore, they should make their affair built upon adherence and imitation and not innovation, upon sincerity and not association of partners (in Allaah's worship), upon the Sunnah and not upon Bid'ah, upon what ar-Rahmaan loves and not upon what Shaytaan loves. Then they should look at the security, life and tranquility that their hearts will obtain and also the ease and comfort of their condition.
I ask Allaah that He makes us guides who are guided and leaders of the righteous. That He enlightens our hearts with faith and knowledge and that He does not make the knowledge we have aqcuired harmful to us. That He travels with us upon the path of His believing servants and that He makes us from among His close friends who have fear of him and among His party of the succesful ones. May Allaah send prayers and blessings upon our Prophet Muhammad, his family and his companions.
