[Machine] To pray the dawn prayer, but not to pray other prayers.  

أَنْ يُثَوِّبَ فِي صَلَاةِ الصُّبْحِ وَلَا يُثَوِّبَ فِي غَيْرِهَا  

[Machine] The Messenger of Allah ﷺ instructed me not to perform any tasbih (prayer) except during dawn, and this is also confirmed. It is narrated by Al-Hajjaj ibn Artat from Talhah ibn Musarrif and Zubayd from Suwayd ibn Ghafalah that Bilal used to only perform tasbih during dawn. So, he would say in his call to prayer, "Hayya 'ala al-falah, as-salatu khayrun min an-nawm" (Hasten to success, prayer is better than sleep).  

أَمَرَنِي رَسُولُ اللهِ ﷺ أَنْ لَا أُثَوِّبَ إِلَّا فِي الْفَجْرِ وَهَذَا أَيْضًا مُرْسَلٌ فَإِنَّ عَبْدَ الرَّحْمَنِ بْنَ أَبِي لَيْلَى لَمْ يَلْقَ بِلَالًا وَرَوَاهُ الْحَجَّاجُ بْنُ أَرْطَاةَ عَنْ طَلْحَةَ بْنِ مُصَرِّفٍ وَزُبَيْدٍ عَنْ سُوَيْدِ بْنِ غَفَلَةَ أَنَّ بِلَالًا كَانَ لَا يُثَوِّبُ إِلَّا فِي الْفَجْرِ فَكَانَ يَقُولُ فِي أَذَانِهِ حِيَّ عَلَى الْفَلَاحِ الصَّلَاةُ خَيْرٌ مِنَ النَّوْمِ  

Mujahid reported: I was in the company of Ibn Umar. A person invited the people for the noon or afternoon prayer (after the adhan had been called). He said: Go out with us (from this mosque) because this is an innovation (in religion). (Using translation from Abū Dāʾūd 538)   

اخْرُجْ بِنَا فَإِنَّ هَذِهِ بِدْعَةٌ
