"كُل كَلام لَا يبدَأ فيهِ بحَمْدِ الله فَهوَ أجْذَمُ".
The Prophet ﷺ said: Every important matter which is not begun by an expression of praise to Allah is maimed. Abu Dawud said: It has also been transmitted by Yunus, 'Aqil, Shu'aib, Sa'id b. 'Abd al-Aziz from al-Zuhri from the Prophet ﷺ in Mursal form (the link of the Companion is missing).
قَالَ رَسُولُ اللَّهِ ﷺ كُلُّ كَلاَمٍ لاَ يُبْدَأُ فِيهِ بِ الْحَمْدُ لِلَّهِ فَهُوَ أَجْذَمُ
ذِكْرُ الْإِخْبَارِ عَمَّا يَجِبُ عَلَى الْمَرْءِ مِنَ ابْتِدَاءِ الْحَمْدِ لِلَّهِ جَلَّ وَعَلَا فِي أَوَائِلِ كَلَامِهِ عِنْدَ بُغْيَةِ مَقَاصِدِهِ
the Messenger of Allah said: “Every important matter that does not start with praise of Allah, is devoid (of blessings).” (Using translation from Ibn Mājah 1894)
قَالَ رَسُولُ اللَّهِ ﷺ «كُلُّ أَمْرٍ ذِي بَالٍ لَا يُبْدَأُ فِيهِ بِحَمْدِ اللَّهِ فَهُوَ أَقْطَعُ»
ذِكْرُ الْأَمْرِ لِلْمَرْءِ أَنْ تَكُونَ فَوَاتِحُ أَسْبَابِهِ بِحَمْدِ اللَّهِ جَلَّ وَعَلَا لِئَلَّا تَكُونَ أَسْبَابُهُ بَتْرًا
the Messenger of Allah said: “Every important matter that does not start with praise of Allah, is devoid (of blessings).” (Using translation from Ibn Mājah 1894)
قَالَ رَسُولُ اللَّهِ ﷺ «كُلُّ أَمْرٍ ذِي بَالٍ لَا يُبْدَأُ فِيهِ بِحَمْدِ اللَّهِ أَقْطَعُ»
"كل أمْر ذي بَال لا يبدَأ فيهِ بِحَمْدِ الله فَهُوَ أقْطَعُ".
