Excellence and Etiquette of Sincere love for the sake of Allah
وَعَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسلم إِن اللَّه تَعَالَى يَقُولُ يَوْمَ الْقِيَامَةِ أَيْنَ الْمُتَحَابُّونَ بجَلَالِي؟ الْيَوْمَ أُظِلُّهُمْ فِي ظِلِّي يَوْمَ لَا ظِلَّ إِلَّا ظِلِّي (( رَوَاهُ مُسْلِم)) .
Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah (ﷺ) said, "On the Day of Resurrection, Allah, the Exalted, will say: 'Where are those who have mutual love for the sake of My Glory? Today I shall shelter them in My Shade when there will be no shade except Mine". [Muslim].
