Between the green markers during sa'i, men should increase their pace to a jog, commemorating Hajar's desperate search for water. Recite: 'Rabbighfir warham, innaka Antal-A'azzul-Akram' — O Lord, forgive and have mercy, for You are the Most Mighty, the Most Noble. Continue with personal doa-doa and dhikr.
رَبِّ اغْفِرْ وَارْحَمْ، إِنَّكَ أَنْتَ الْأَعَزُّ الْأَكْرَمُ
Rabbighfir warham, innaka Antal-A'azzul-Akram.
Meaning: O Lord, forgive and have mercy, for You are the Most Mighty, the Most Noble.
Source: Muwatta Malik #836The green markers indicate the valley (batn al-wadi) where Hajar (peace be upon her) ran desperately searching for water for her infant son Isma'il. This section commemorates her trust in Allah during the most dire circumstances. Allah rewarded her perseverance with the miraculous spring of Zamzam, which continues to flow to this day. Walking briskly here is an act of remembrance of her devotion.
رَبِّ اغْفِرْ وَارْحَمْ، إِنَّكَ أَنْتَ الْأَعَزُّ الْأَكْرَمُ
It was reported from the companions and the Tabi'in that they would recite 'Rabbighfir warham, innaka Antal-A'azzul-Akram' between the green markers during Sa'i, and would make personal supplication throughout.
