عَنِ ابْنِ عَبَّاسٍ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((لَا نِكَاحَ إِلَّا بِوَلِيٍّ وَالسُّلْطَانُ وَلِيُّ مَنْ لَا وَلِيَّ لَهُ))
Narrated by Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both): The Noble Prophet (peace and blessings be upon him) said: There is no marriage without a guardian, and whoever has no guardian, the Sultan will be her guardian.
