Hārithah ibn Wahb (may Allah be pleased with him) reported that the Messenger of Allah (may Allah’s peace and blessings be upon him) said: "Should I not inform you about the people of Paradise? Every weak person who is looked down upon; if he were to make an oath in the name of Allah, He (Allah) would fulfill it." He then said: "Should I not inform you about the people of Hellfire? Every cruel, greedy, and arrogant person."
عن حارثة بن وهب -رضي الله عنه- مرفوعًا: «ألا أُخْبِركم بأهل الجنة؟ كلُّ ضعيفٍ مُتَضَعَّفٍ، لو أقسم على الله لَأَبَرَّهُ، ألا أُخْبِركم بأهل النار؟ كُلُّ عُتُلٍّ جَوَّاظٍ مُسْتَكْبِرٍ».
شرح الحديث :
From the attributes of the people of Paradise is that a person is weak and looked at as being humble and weak. This means that he is indifferent to his position and status nor seeks after high ranks in this world. If this person were to swear by Allah, Allah will facilitate it for him so that He fulfills the oath. As for the people of Hellfire, they are cruel and harsh and disobedient to the truth. They build their wealth without distributing the obligatory Zakah among the needy. They reject the truth out of arrogance. This Hadīth does not limit the traits of either party but rather reveals some of them.
