Adding the words, “ونَسْتَهْدِيْهِ And we seek His Guidance,” or “… وَنَتُوْبُ إِلَيْهِ … we turn to Him in repentance,” to the Khutbatul-Haajah
“Our Shaikh, may Allaah have mercy on him, said in Silsilah al-Ahadith as-Saheehah (5/6), “I have heard more than one person from the preachers increasing upon this by saying, ‘ ونَسْتَهْدِيْهِ … and we seek His Guidance …’! And while we thank them for reviving this sermon [of need], [using it] in their sermons and lectures, [at the same time] we see it incumbent upon us to remind them that this addition has no basis reported in any of the paths of narration through which this sermon is reported–the Sermon of Need–which I had gathered in a well-known treatise specifically about it, ‘And remind, for reminding profits the believers.’” [Dhaariyaat 51:55].
And in [his book] ‘The Advice’ on page 77 he said, “And the wording, ‘ونَسْتَهْدِيْهِ … and we seek His Guidance …’ is an addition which has no basis in any of the paths of narration of the hadith. And I hear this addition, ‘… and we seek His Guidance …’ many times from some of the notable preachers in some of the Arab countries, and for this reason it is necessary to point it out because the words of remembrance with Ahlus-Sunnah are bound by a religious text and not amenable to personal opinion [tawqi̱fi̱yah], as is known from the Sunnah.”
And he said in, ‘The Decisive Refutation,’ on page 5, “Some of the preachers, and other than them, add [the wording], ‘ونَسْتَهْدِيْهِ … and we seek His Guidance …’ or other than it like, ‘وَنَتُوْبُ إِلَيْهِ … and we turn to Him in repentance …,’ so it should be noted that that has not been reported and it is not permissible to increase upon the teaching of the Prophet صلى الله عليه وسلم, as is known.”
