The Companion al-Harith ibn Hisham asked the Prophet ﷺ how the revelation came to him: his question opens the second hadith of Sahih al-Bukhari (al-Bukhari 2). A hadith whose authenticity is disputed says: “The truest of names are Harith and Hammam” (Abu Dawud 4950); the commentators explain that every man works to earn his living (ḥarth) and forms intentions (hamm).
Meaning of the name Harith
Harith is the active participle of haratha, “to plough, to till the land” (root ḥ-r-th): it means the ploughman and, more broadly, one who works to earn his living, since ḥarth also means gain. The Quran uses the word figuratively: “Whoever desires the harvest of the Hereafter, We increase him in his harvest” (42:20). Abu al-Harith is a by-name of the lion. Often borne with the article (al-Harith), the name is one of the oldest among the Arabs.
Whoever desires the harvest of the Hereafter - We increase for him in his harvest [i.e., reward]. And whoever desires the harvest [i.e., benefits] of this world - We give him thereof, but there is not for him in the Hereafter any share.
Your wives are a place of cultivation [i.e., sowing of seed] for you, so come to your place of cultivation however you wish and put forth [righteousness] for yourselves. And fear Allāh and know that you will meet Him. And give good tidings to the believers.
He said, "He says, 'It is a cow neither trained to plow the earth nor to irrigate the field, one free from fault with no spot upon her.'" They said, "Now you have come with the truth." So they slaughtered her, but they could hardly do it.
