Jihad is to be carried on whether the Muslim ruler is good or bad

Narrated 'Urwa Al-Bariqi:

The Prophet ﷺ said, "Good will remain (as a permanent quality) in the foreheads of horses (for Jihad) till the Day of Resurrection, for they bring about either a reward (in the Hereafter) or booty (in this world."

حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا زَكَرِيَّاءُ، عَنْ عَامِرٍ، حَدَّثَنَا عُرْوَةُ الْبَارِقِيُّ، أَنَّ النَّبِيَّ ﷺ قَالَ " الْخَيْلُ مَعْقُودٌ فِي نَوَاصِيهَا الْخَيْرُ إِلَى يَوْمِ الْقِيَامَةِ الأَجْرُ وَالْمَغْنَمُ ".
