At-Tawbah 9:74 يحلفون بالله ما قالوا ولقد قالوا كلمة الكفر وكفروا بعد اسلامهم وهموا بما لم ينالوا وما نقموا الا ان اغناهم الله ورسوله من فضله فان يتوبوا يك خيرا لهم وان يتولوا يعذبهم الله عذابا اليما في الدنيا والاخرة وما لهم في الارض من ولي ولا نصير ٧٤

They swear by Allâh that they said nothing (bad), but really they said the word of disbelief, and they disbelieved after accepting Islâm, and they resolved that (plot to murder Prophet Muhammad صلى الله عليه وسلم) which they were unable to carry out, and they could not find any cause to do so except that Allâh and His Messenger had enriched them of His Bounty. If then they repent, it will be better for them, but if they turn away, Allâh will punish them with a painful torment in this worldly life and in the Hereafter. And there is none for them on earth as a Walî (supporter, protector) or a helper.
