The Companions of the Prophet (may Allah's peace and blessings be upon him) were the most keen among people on doing good, and they would constantly look for deeds that increased their rewards with Allah Almighty. In this Hadīth, ’Ubayy ibn Ka‘b (may Allah be pleased with him) relates that there was a man from the Prophet's Companions from the Ansār - the people of Madīnah - and it is mentioned in Musnad that he was the cousin of ’Ubayy ibn Ka‘b (may Allah be pleased with both of them), whose house was the farthest house from the Prophet's Mosque. Despite the remoteness of his house, he would not miss the prayer in the mosque with the Prophet (may Allah's peace and blessings be upon him). The Companions (may Allah be pleased with them) felt pity for him for the hardship and tiredness he would go through while coming and going back. So, they said to him: If you buy a donkey, it will shield you from the heat of the scorching sand; and it will shield you from the vermin of the earth. Vermin is a term that refers to creatures with lethal poison, like serpents, and it may also refer to creatures that are not to be killed, such as insects. He swore by Allah to them that he would not like his house to be adjacent to the Prophet's house; rather, he liked that it be far away from it, so that his reward would increase with the increase of steps he would take from his house to the mosque. He did not intend to negate his love for being close to the house of the Messenger of Allah (may Allah's peace and blessings be upon him) out of hatred for him, but in the hope of a greater reward with the increase of those steps. ’Ubayy ibn Ka‘b (may Allah be pleased with him) assumed by his statement that he meant hatred for the Prophet (may Allah's peace and blessings be upon him). So, ’Ubayy (may Allah be pleased with him) said: "I was troubled by that" i.e., I found that to be grave and was distressed by it, given the repugnance and horridness of what he said and its evil connotation, namely that he hated the Prophet (may Allah's peace and blessings be upon him). In a version by Ahmed, he said: "I have not heard a statement about him more hateful to me than it." ’Ubayy ibn Ka‘b (may Allah be pleased with him) interpreted his statement wrongly and thought ill of it because Madīnah abounded with hypocrites at the time, and they were keen to live away from the Messenger of Allah (may Allah's peace and blessings be upon him). Then, ’Ubayy ibn Ka‘b came to the Prophet of Allah (may Allah's peace and blessings be upon him) and informed him about what this man said. So, the Prophet (may Allah's peace and blessings be upon him) sent for him, and he said the same to him as he said to ’Ubayy ibn Ka‘b, and he mentioned to the Prophet (may Allah's peace and blessings be upon him) that what made him say so was that he hoped for and pursued reward and recompense from Allah for his walking. Thereupon, the Prophet (may Allah's peace and blessings be upon him) said to him: "You will have what you hoped for", i.e., Allah Almighty will give you the reward for your steps which you took for the sake of Allah, Exalted be He, and kept in store with Him. Hoping for reward means that one performs a deed for the sake of Allah and thereby seeks recompense and reward from Allah. The Hadīth points out the merit of walking to the mosques..
