Abud Darda’ reported God’s messenger as saying, “The best thing in which to visit God in your graves and in your mosques is white." Ibn Majah transmitted it.

وَعَنْ أَبِي الدَّرْدَاءِ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّ أَحْسَنَ مَا زُرْتُمُ اللَّهَ فِي قُبُورِكُمْ وَمَسَاجِدِكُمُ الْبَيَاضُ» . رَوَاهُ ابْن مَاجَه
