And if you fear [an enemy, then pray] on foot or riding. But when you are secure, then remember Allāh [in prayer], as He has taught you that which you did not [previously] know. (Surah Al-Baqarah, 2:239)

وَهُوَ الَّذِي أَنزَلَ مِنَ السَّمَاءِ مَاءً فَأَخْرَجْنَا بِهِ نَبَاتَ كُلِّ شَيْءٍ فَأَخْرَجْنَا مِنْهُ خَضِرًا نُّخْرِجُ مِنْهُ حَبًّا مُّتَرَاكِبًا وَمِنَ النَّخْلِ مِن طَلْعِهَا قِنْوَانٌ دَانِيَةٌ وَجَنَّاتٍ مِّنْ أَعْنَابٍ وَالزَّيْتُونَ وَالرُّمَّانَ مُشْتَبِهًا وَغَيْرَ مُتَشَابِهٍ انظُرُوا إِلَىٰ ثَمَرِهِ إِذَا أَثْمَرَ وَيَنْعِهِ إِنَّ فِي ذَٰلِكُمْ لَآيَاتٍ لِّقَوْمٍ يُؤْمِنُونَ ٩٩

مُّتَرَاكِبًا mutarākiban · thick clustered

And it is He who sends down rain from the sky, and We produce thereby the growth of all things. We produce from it greenery from which We produce grains arranged in layers. And from the palm trees - of its emerging fruit are clusters hanging low. And [We produce] gardens of grapevines and olives and pomegranates, similar yet varied. Look at [each of] its fruit when it yields and [at] its ripening. Indeed in that are signs for a people who believe. (Surah Al-An'am, 6:99)

إِذْ أَنتُم بِالْعُدْوَةِ الدُّنْيَا وَهُم بِالْعُدْوَةِ الْقُصْوَىٰ وَالرَّكْبُ أَسْفَلَ مِنكُمْ وَلَوْ تَوَاعَدتُّمْ لَاخْتَلَفْتُمْ فِي الْمِيعَادِ وَلَٰكِن لِّيَقْضِيَ اللَّهُ أَمْرًا كَانَ مَفْعُولًا لِّيَهْلِكَ مَنْ هَلَكَ عَن بَيِّنَةٍ وَيَحْيَىٰ مَنْ حَيَّ عَن بَيِّنَةٍ وَإِنَّ اللَّهَ لَسَمِيعٌ عَلِيمٌ ٤٢

وَالرَّكْبُ wal-rakbu · and the caravan

[Remember] when you were on the near side of the valley, and they were on the farther side, and the caravan was lower [in position] than you. If you had made an appointment [to meet], you would have missed the appointment. But [it was] so that Allāh might accomplish a matter already destined - that those who perished [through disbelief] would perish upon evidence and those who lived [in faith] would live upon evidence; and indeed, Allāh is Hearing and Knowing. (Surah Al-Anfal, 8:42)

وَذَلَّلْنَاهَا لَهُمْ فَمِنْهَا رَكُوبُهُمْ وَمِنْهَا يَأْكُلُونَ ٧٢

رَكُوبُهُمْ rakūbuhum · they ride them

And We have tamed them for them, so some of them they ride, and some of them they eat. (Surah Ya-Sin, 36:72)
