Quran 20:96 Taha, ayah 96 of 135

قَالَ بَصُرْتُ بِمَا لَمْ يَبْصُرُوا۟ بِهِۦ فَقَبَضْتُ قَبْضَةً مِّنْ أَثَرِ ٱلرَّسُولِ فَنَبَذْتُهَا وَكَذَٰلِكَ سَوَّلَتْ لِى نَفْسِى ۝٩٦

20:96 He said: I perceived what they perceive not, so I seized a handful from the footsteps of the messenger, and then threw it in. Thus my soul commended to me.
