When leaving Arafat at sunset, continue with Talbiyah and istighfar. The Prophet departed calmly, saying: 'O people, be calm. Righteousness is not in rushing.' He continued reciting the Talbiyah and seeking forgiveness throughout the journey to Muzdalifah. Make your final intense duas before sunset.
لَبَّيْكَ اللَّهُمَّ لَبَّيْكَ، لَبَّيْكَ لَا شَرِيكَ لَكَ لَبَّيْكَ. أَسْتَغْفِرُ اللَّهَ الَّذِي لَا إِلَٰهَ إِلَّا هُوَ الْحَيُّ الْقَيُّومُ وَأَتُوبُ إِلَيْهِ
Labbayk Allahumma labbayk, labbayka la sharika laka labbayk. Astaghfirullaha-lladhi la ilaha illa Huwal-Hayyul-Qayyumu wa atubu ilayh.
Meaning: Here I am, O Allah, here I am. Here I am, You have no partner, here I am. I seek the forgiveness of Allah, there is no god but He, the Ever-Living, the Self-Sustaining, and I repent to Him.
Source: Sahih al-Bukhari #1666The departure from Arafat at sunset marks the transition from the most blessed day of the year to the night at Muzdalifah. The Prophet (peace be upon him) emphasized calmness and dignity during this departure, warning against rushing. He continued the Talbiyah and istighfar, maintaining the spiritual state of humility and devotion cultivated throughout the Day of Arafat.
لَبَّيْكَ اللَّهُمَّ لَبَّيْكَ، لَبَّيْكَ لَا شَرِيكَ لَكَ لَبَّيْكَ. أَسْتَغْفِرُ اللَّهَ الَّذِي لَا إِلَٰهَ إِلَّا هُوَ الْحَيُّ الْقَيُّومُ وَأَتُوبُ إِلَيْهِ
I was riding behind the Prophet (peace be upon him) when he departed from Arafat. He kept pulling the reins of his camel to slow it down, saying: 'O people, be calm, for righteousness is not in rushing.' He continued reciting the Talbiyah until he reached Muzdalifah.
