Sahih Muslim #1218Sahih
إِنَّ الصَّفَا وَالْمَرْوَةَ مِنْ شَعَائِرِ اللَّهِ، أَبْدَأُ بِمَا بَدَأَ اللَّهُ بِهِ. لَا إِلَٰهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ، لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ، لَا إِلَٰهَ إِلَّا اللَّهُ وَحْدَهُ، أَنْجَزَ وَعْدَهُ، وَنَصَرَ عَبْدَهُ، وَهَزَمَ الْأَحْزَابَ وَحْدَهُ
The Prophet (peace be upon him) began with Safa. He climbed it until he could see the Ka'bah, then he faced the Qiblah, declared the Oneness of Allah, magnified Him, and said: 'La ilaha illallahu wahdahu la sharika lah...' He made dua between that, saying this three times.
