Allah made it possible for Ababeel to carry stones as per Quran WHERE DOES IT SAY IN QURAN FOR FATIMA TO COLLECT THE TEARS IN THE BOTTLE KUN FA YAKUN do you understand that?
Why would Allah need to send a message to Maulatena Fatema AS everytime via Holy Quran when Allah can have His Angel directly carry a message to Maulatena Fatema AS?
Did Allah send a written message (book, telegram, email, speedpost etc) to Maulatena Maryam AS regarding the birth of Prophet Jesus AS? No, the Holy Quran tells us that He sent His Angel with the message to Maulatena Maryam AS. [Holy Quran, surah Maryam, Ayat 17, Holy quran 19:17]
So when an Angel can directly carry a message from Allah to the mother of a Prophet, why can't an Angel carry a message by the command of Allah to the daughter of his most beloved Prophet(SAWW).
Who are you to insist that Allah should send only a written message (via Holy Quran) everytime He wishes to command His beloved Prophet's(SAWW) daughter to perform some action?
