The Satan comes to everyone. of you and says: Who created this and that? till he questions: Who created your Lord? When he comes to that, one should seek refuge in Allah and keep away (from such idle thoughts).
قَالَ رَسُولُ اللَّهِ ﷺ يَأْتِي الشَّيْطَانُ أَحَدَكُمْ فَيَقُولُ مَنْ خَلَقَ كَذَا وَكَذَا حَتَّى يَقُولَ لَهُ مَنْ خَلَقَ رَبَّكَ فَإِذَا بَلَغَ ذَلِكَ فَلْيَسْتَعِذْ بِاللَّهِ وَلْيَنْتَهِ
Messenger of Allah ﷺ said, "Satan comes to one of you and says, 'Who created so-and-so? 'till he says, 'Who has created your Lord?' So, when he inspires such a question, one should seek refuge with Allah and give up such thoughts."
قَالَ رَسُولُ اللَّهِ ﷺ يَأْتِي الشَّيْطَانُ أَحَدَكُمْ فَيَقُولُ مَنْ خَلَقَ كَذَا مَنْ خَلَقَ كَذَا حَتَّى يَقُولَ مَنْ خَلَقَ رَبَّكَ فَإِذَا بَلَغَهُ فَلْيَسْتَعِذْ بِاللَّهِ وَلْيَنْتَهِ
"يَأتِى الشَّيْطَانُ أحَدَكُمْ فَيَقُولُ: مَنْ خَلَقَ كَذَا؟ مَنْ خَلَقَ كَذَا؟ حَتَّى يَقُولَ: مَنْ خَلَقَ رَبَّكَ؟ فَإِذَا بَلَغَهُ فَلْيَسْتَعِذْ بِاللَّه وَلْيَنْتَهِ".
