عَنْ عُبَادَةَ بْنِ الصَّامِتِ رَضِيَ اللَّهُ عَنْهُ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «مَنْ شَهِدَ أَنْ لَا إِلَهَ إِلَّا اللَّهُ وَأَنَّ مُحَمَّدًا رَسُولُ اللَّهِ حَرَّمَ الله عَلَيْهِ النَّار»
Translation
‘Amr b. ‘Abasa said

I came to God's messenger and asked, “Who is associated with you in this matter, messenger of God?” He replied, “Both freeman and slave.” I asked what Islam was and he said, I “Pleasant speech and the provision of food.” I asked what faith was and he said, “Endurance and benevolence.” I asked what aspect of Islam was most excellent, and he replied that it was to be seen in him from whose tongue and hand the Muslims were safe. I asked what aspect of faith was most excellent, and he replied that it was a good disposition. I asked what feature of prayer was most excellent, and he replied that it consisted in standing for a long time in [silent] humility. I asked him what aspect of emigration (hijra) was most excellent, and he replied, “Abandoning (an tahjura) what your Lord abhors.” I asked what aspect of jihad was most excellent, and he replied that it was when a man’s steed was wounded and his blood was shed. I asked him which hour was most excellent, and he replied that it was towards the end of the darkest part of the night. Ahmad transmitted it.
