al Nawawi and scholars of his time on the ignorant who would start worshiping the tree under which Prophet peace be upon him took bayt Ridwan.
Al Nawawi said:
’’قال العلماء سبب خفائها أن لا يفتتن الناس بها لما جرى تحتها من الخير ونزول الرضوان والسكينة وغير ذلك فلو بقيت ظاهرة معلومة لخيف تعظيم الأعراب والجهال إياها وعبادتهم لها فكان خفاؤها رحمة من الله تعالى‘‘
The scholars mentioned the reason of its (the tree’s) concealment is that, people should not be fascinated by it because of the good that took place under it, If it remained a known, it would be feared that the Bedouins and ignorant people would start venerating and worshiping it, so its concealment is a mercy from Allah Almighty.”
