Allah allows a person's thoughts and whatever occurs in his heart so long as they do not become established
Sahih Muslim
وَحَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا مِسْعَرٌ، وَهِشَامٌ، ح وَحَدَّثَنِي إِسْحَاقُ بْنُ مَنْصُورٍ، أَخْبَرَنَا الْحُسَيْنُ بْنُ عَلِيٍّ، عَنْ زَائِدَةَ، عَنْ شَيْبَانَ، جَمِيعًا عَنْ قَتَادَةَ، بِهَذَا الإِسْنَادِ مِثْلَهُ .
The same hadith has been narrated by Zuhair b. Harb, Waki, Ishaq b. Mansur, Husain b. 'Ali.
