Ibn Umar reported: We were with the Messenger of Allah, peace and blessings be upon him, on a journey and a bedouin passed by us. When he came near, the Prophet said, “Where are you going?” He said, “I am going to my people.” The Prophet said, “Would you like to bring goodness with you?” He said, “What is it?” The Prophet said, “That you witness there is no God but Allah alone without any partners and that Muhammad is the servant of Allah and His Messenger.” He said, “Who will bear witness to what you say?” The Prophet said, “This tree is a witness.” The Prophet called the tree from the edge of the valley and it ploughed through the earth as it came until it stood before him. The Prophet asked for its testimony and it bore witness three times that he is the Messenger of Allah. Then it returned to the place where it grew. The Bedouin returned to his people and he said, “If they follow me, I will bring them all to you. Otherwise, I will return alone with you.”

عَنْ ابْنِ عُمَرَ قَالَ كُنَّا مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي سَفَرٍ فَأَقْبَلَ أَعْرَابِيٌّ فَلَمَّا دَنَا مِنْهُ قَالَ لَهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَيْنَ تُرِيدُ قَالَ إِلَى أَهْلِي قَالَ هَلْ لَكَ فِي خَيْرٍ قَالَ وَمَا هُوَ قَالَ تَشْهَدُ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ وَأَنَّ مُحَمَّدًا عَبْدُهُ وَرَسُولُهُ قَالَ وَمَنْ يَشْهَدُ عَلَى مَا تَقُولُ قَالَ هَذِهِ السَّلَمَةُ فَدَعَاهَا رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهِيَ بِشَاطِئِ الْوَادِي فَأَقْبَلَتْ تَخُدُّ الْأَرْضَ خَدًّا حَتَّى قَامَتْ بَيْنَ يَدَيْهِ فَاسْتَشْهَدَهَا ثَلَاثًا فَشَهِدَتْ ثَلَاثًا أَنَّهُ كَمَا قَالَ ثُمَّ رَجَعَتْ إِلَى مَنْبَتِهَا وَرَجَعَ الْأَعْرَابِيُّ إِلَى قَوْمِهِ وَقَالَ إِنْ اتَّبَعُونِي أَتَيْتُكَ بِهِمْ وَإِلَّا رَجَعْتُ فَكُنْتُ مَعَكَ
