that the Messenger of Allah ﷺ said: "When one of you writes something, then let him Yutarrib (smeared with dust to dry the ink) it, for that is more conducive to the need." (Using translation from Tirmidhī 2713)
"إذا كتبَ أحدُكُمْ كتابًا فلْيُتَرِّبْهُ، فإِنَّ التُّرابُ مُباركٌ، وَهْوَ أنْجحُ للحاجة".
