What is the supplication that can be recited upon passing by a verse of prostration while reciting the Quran without being able to prostrate immediately?

There is no supplication or remembrance that can substitute for the prostration of recitation (Sujud al-Tilawah). Moreover, it is not obligatory, as evidenced by what Al-Bukhari narrated from Umar ibn Al-Khattab, may Allah be pleased with him, who said: "O people, we pass by the prostration (of recitation), so whoever prostrates has done well, and whoever does not prostrate incurs no sin." And Umar, may Allah be pleased with him, did not prostrate.
