‘Abd Allah bin ‘Umar said “When the Apostle of Allaah(ﷺ) returned from an expedition, Hajj or ‘Umrah on every rising piece of ground he would say three times “Allaah is Most Great” and he would say “There is no god bt Allaah alone who has no partner, to Whom the dominion belongs, to Whom praise is due, and Who is Omnipotent, serving, prostrating ourselves before our Lord and expressing praise. Allaah alone has kept his word, helped His servant and routed the confederate.
حَدَّثَنِي الْقَعْنَبِيُّ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم كَانَ إِذَا قَفَلَ مِنْ غَزْوٍ أَوْ حَجٍّ أَوْ عُمْرَةٍ يُكَبِّرُ عَلَى كُلِّ شَرَفٍ مِنَ الأَرْضِ ثَلاَثَ تَكْبِيرَاتٍ وَيَقُولُ " لاَ إِلَهَ إِلاَّ اللَّهُ وَحْدَهُ لاَ شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَىْءٍ قَدِيرٌ آيِبُونَ تَائِبُونَ عَابِدُونَ سَاجِدُونَ لِرَبِّنَا حَامِدُونَ صَدَقَ اللَّهُ وَعْدَهُ وَنَصَرَ عَبْدَهُ وَهَزَمَ الأَحْزَابَ وَحْدَهُ " .
