About the book Al-Durrat Al-Bayda, what its author mentioned:
This is a blessed message that I called “The White Pearl”, which collected - praise be to God - the core of the secrets of the tolerant Sharia, and the glorious way, in which the righteous rejoice, and those who seek the truth rush to it, and those who fail are repelled from it, and it is nothing but a true verse, quoted from the Book of God and the Sunnah of the Messenger of God. , upon him is the most complete and most general of the blessings of God, it is pure as its name, so seize it, O loving, intelligent lover, for it is one of the gentle prophetic scents, and one of those who know the blessings of the chosen ones.

What he said about the bulbul number:
He says: The poor servant - in all cases - to God is Muhammad Mahdi, nicknamed Baha al-Din, who is called in the presence of the strangers, and nicknamed Abu Al-Barahin Ibn Ali Al-Khuzam Al-Sayyadi Al-Rifai Al-Husseini and then Al-Rudaini. May God be with him, his parents and the Muslims, Amen. In the year two hundred and fifty-two I was in Makkah Al-Mukarramah, in the Sacred House of God, and I faced the qiblah and occupied myself with the remembrance of God Almighty.
So I heard a nightingale tying in a language I had heard in the presence of the presence, and an unseen man taught me it, by a prophetic order, so I understood what the nightingale was numbered with, addressing a companion of his, so I wrote his words and the answer that was given to him in these blessed pages. And the strangest oddities, the secret of which is known by those who know, the investigators benefit from it, and the conciliators are humbled by its content, and the matter is between the Kaf and the Nun.
