Quran 20:96 from Surah Taa-Haa on Divine Marvels.
قَالَ بَصُرۡتُ بِمَا لَمۡ يَبۡصُرُواْ بِهِۦ فَقَبَضۡتُ قَبۡضَةٗ مِّنۡ أَثَرِ ٱلرَّسُولِ فَنَبَذۡتُهَا وَكَذَٰلِكَ سَوَّلَتۡ لِي نَفۡسِي
English translation: He said I perceived what not they perceive in it so I took a handful from (the) track (of) the Messenger then threw it and thus suggested to me my soul
Transliteration: qala basur'tu bima lam yabsuru bihi faqabadtu qabdatan min athari al-rasuli fanabadhtuha wakadhalika sawwalat li nafsi
