Is it sufficient to go directly to Arafat on the Day of Arafah without performing the Tawaf Al-Qudum (Tawaf of Arrival) and Sa'y (ritual walk between Safa and Marwah), then returning to perform Tawaf Al-Ifadah (Tawaf of Overflowing) and the Sa'y of Hajj after stoning the Jamarat? And is one intention sufficient for both Tawaf Al-Qudum and Tawaf Al-Ifadah? And until when is the standing at Arafat sufficient?

The individual performing Hajj (Mufrid) or the one performing both Hajj and Umrah (Qarin) circumambulates the Kaaba for Tawaf Al-Ifadah once if he only entered Mecca on the Day of Sacrifice (Yawm An-Nahr). This suffices for Tawaf Al-Qudum (Tawaf of Arrival). Standing at Arafat begins from the declination of the sun on the ninth day according to the majority of scholars, and from the dawn of the same day according to Ahmad, extending until the dawn of the Day of Sacrifice. It is sunnah (recommended) to combine standing during both night and day to avoid scholarly disagreement.
