Subhan’Allah, I must share this with you now – a fitting excerpt from The Conqueror of Hearts: In the Land of Sultan Muhammad Al-Fateh
… the difference is on account of each person’s capacity. Muhammad (ṣall Allāhu ʿalay-hi wa-sallam) had an unlimited capacity to drink from the river of ma’rifah, so no matter how much he drank, it seemed meager in comparison with how much could be obtained. But Bayazid had a much more limited capacity compared to the Prophet (ṣall Allāhu ʿalay-hi wa-sallam), so after drinking only a glass of that spiritual wine, he felt satiated.
Another day, Maulana Rumi was reading under the shade of a tree by a river, a pile of books beside him–according to one variation he was teaching a group of his students with a pile of hand-written notes next to him–when Shams Tabriz came by. He asked Maulana what was going on and he replied ‘This is qaal (words), something you cannot understand.’ Shamz Tabriz then took Maulana’s precious books and threw them in the water. Maulana was aghast. Shams Tabriz then recited Bismillah and pulled the books out of the water and dusted the water off them as if he was dusting sand; the pages thus dried and Maulana saw that the ink on them had not run despite having been soaked in water. Maulana was amazed and asked incredulously, what is this. ‘This is haal (spiritual state), something you cannot understand,’ replied Shams Tabriz.
