1356 يكشف ربنا عن ساقه، فيسجد له كل مؤمن ومؤمنة، فيبقى كل من كان يسجد في الدنيا رياء وسمعة، فيذهب ليسجد، فيعود ظهره طبقا واحدا
Our Lord will reveal His Shin, and then all believers, men and women, will prostrate themselves before Him, but there will remain those who used to prostrate in the worldly life for showing off and gaining good reputation. Such people will try to prostrate (in that situation) but their backs will be as stiff as if it is one bone

عن أبي سعيد الخدري رضي الله عنه مرفوعاً: «يكشِف ربُّنا عن ساقِه، فيسجدُ له كلُّ مؤمنٍ ومؤمنةٍ، فيبقى كلُّ مَن كان يسجدُ في الدنيا رياءً وسُمْعةً، فيذهبُ ليسجدَ، فيعودَ ظهرُه طبقًا واحدًا».

Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Our Lord will reveal His Shin, and then all believers, men and women, will prostrate themselves before Him, but there will remain those who used to prostrate in the worldly life for showing off and gaining good reputation. Such people will try to prostrate (in that situation) but their backs will be as stiff as if it is one bone (a single vertebra)."

صحيح - ( متفق عليه ). Sahih/Authentic. [Al-Bukhari and Muslim]

يكشف الرب سبحانه وتعالى عن ساقه الكريمة، فيسجد له كل مؤمن ومؤمنة، وأما المنافقون الذين كانوا يسجدون في الدنيا ليراهم الناس، فمُنعوا من السجود، وجُعلت ظهورهم فقارًا واحدًا، لا يستطيعون الانحناء ولا السجود؛ لأنهم ما كانوا في الحقيقة يسجدون لله في الدنيا، وإنما كانوا يسجدون لأغراضهم الدنيوية، ولا يجوز تأويل الساق بالشدة أو الكرب أو غيرها، بل يجب إثباتها صفة لله تعالى من غير تكييف ولا تمثيل، ومن غير تحريف ولا تعطيل.
The Lord, Glorified and Exalted, will reveal His noble Shin on the Day of Judgment, and every believer, male and female, will prostrate to Him. As for the hypocrites who used to prostrate to Allah in the worldly life so as to be seen by people, they will not be able to prostrate because their backs will be made of one vertebra or one straight bone. They will not be able to bend nor prostrate, because they did not really prostrate to Allah in the worldly life, rather they only prostrated to their worldly purposes. It is not permissible to interpret Allah's Shin as hardship, distress and so on. Rather it is obligatory to affirm this attribute for Allah, the Almighty, without asking 'how', and without drawing resemblance or similitude, and without stripping it of its true meaning.

الساق صفة لله -تعالى- حيث عرفه المؤمنون بذلك فسجدوا له. التحذير من الرياء.
