Is it permissible to supplicate using the words of the poem "Aghibu wa dhu al-lata'if la yaghib" (I may be absent, but the Lord of Subtleties is never absent) because it contains praise and hope in Allah?

The best approach is to supplicate with the prayers found in the Qur’an and Sunnah. Scholars have denounced supplicating with rhymed words and those chosen from the expressions of poets, considering such acts as transgressing in supplication. Nevertheless, we do not see an absolute prohibition against supplicating with rhymed prose (saj') or poetic verse (rajaz), as some jurists have mentioned the permissibility of rhymed supplication if it is memorized or not forced. It is authentically reported that the Prophet (peace be upon him) recited a rajaz of Abdullah ibn Rawaha on the Day of the Trench, and it contained a supplication, and rajaz is a type of poetry. Therefore, it is permissible to supplicate with memorized rhymed verses, and there is no harm upon the supplicant who does so.
