The Source of Traditions on Imam al-Riḍā (Vol 2) · Hadith 43 (#Ḥadīth #43)

43 - وَبِهذَا الإِسنادِ قالَ: قالَ رَسُولُ اللَّهِ صَلَّى اللهُعَلَيْهِ وَآلِهِ: إِنَّ لِلَّهِ عَزَّ وَجَلَّ عَمُوداً مِن ياقوتٍ أَحمَرَ؛ رَأسَهُ تَحْتَ العَرْشِ وَأَسفَلَهُ عَلَى ظَهرِ الحُوتِ فِي الأَرْضِ السَّابِعَةِ السُّفلَى؛ فَإِذا قالَ العَبْدُ: لا إِلهَ إِلّا اللَّهُ وَحْدَهُ لا شَرِيكَ لَهُ إِهتَزَّ العَرْشُ، وَتَحَرَّكَ العَمُود، وَتَحَرَّكَ الحُوت؛ فَيَقُولُ اللَّهَ عَزَّ وَجَلَّ: اسكُن يا عرشِي؛ فَيَقُولُ: يا رَبِّ كَيْفَ أسكُنُ وَأَنْتَلَمْ تَغفِر لِقائِلِها؛ فَيَقُولُ اللَّهُ تَبارَكَ وَتَعالى: اِشْهَدُوا سُكَّانَ سَمَواتِي إِنِّي قَدْ غَفَرتُ لِقائِلِها.

31-43 According to the same documentation, God’s Prophet (S) said, “There is a pillar for the Honorable the Exalted God built of red hyacinth. The head of the pillar is under the Throne, while its other end is on the back of a whale beneath the seventh level of the Earth. Whenever a servant (i.e. a person) says, “There is no god but God. He is One. There are no partners for Him” the Throne will shake, the pillar will move and the whale will move. The Honorable the Exalted God will say, “O My Throne! Relax!” The Throne will reply, “O my Lord! How can Irelax while You have not forgiven the one who said this?” The Blessed the Sublime God will say, “O residents of the heavens! Bear witness that I have forgiven him.”
