43 - حَدَّثَنا مُحَمَّدُ بْنُ الحَسَن بْنِ أَحْمَـدِ بْنِ الوَلِيـد رَضِىَ اللهُ عَنْهُ قالَ: حَدَّثَنـا سَعْدُ بْنُعَبْدِ اللَّه عَنْ إِبْراهيمِ بْنِ هاشِمٍ، عَنْ إِبْراهيمِ بْنِ أَبي مَحْمُودٍ قالَ: رَأَيْتُ الرِّضَا عَلَيْهِ السَّلامُ وَدَّعَ الْبَيْتَ فَلَمَّا أَرَادَ أَنْ يَخْرُجَ مِنْ بَابِ الْمَسْجِدِ خَرَّ سَاجِداً ثُمَّ قَامَ فَاسْتَقْبَلَ الْكَعْبَةَ وَقَالَ: (اللَّهُمَّ إِنِّي أَنْقَلِبُ عَلَى أَنْ لا إِلَهَ إِلا اللَّهُ).

30-43 Muhammad ibn Al-Hassan ibn Ahmad ibn al-Waleed - may God be pleased with him - narrated that Sa’d ibn Abdullah quoted on theauthority of Ibrahim ibn Hashem, on the authority of Ibrahim ibn Abi Mahmood, “I saw Al-Ridha (s) say farewell to the House (of God). When he wanted to leave the mosque door, he (s) fell into prostration. Then he stood up, faced the Qibla - direction of prayer - and said, ‘O my God! I will return with the belief that there is no god but Thee.’”
