Islam persuades its followers to earn livelihood through fair means and it values their struggle for Rizq-e-Halal (lawful sustenance).
The pious predecessors رَحِمَهُمُ اللّٰە also chose a lawful source of income. The second caliph, Ameer-ul-Mu’mineen Sayyiduna ‘Umar Farooq-e-A’zam رَضِىَ اللّٰەُ عَنْهُ is also one of such pious personages.
Source of income
Sources of income of Sayyiduna ‘Umar Farooq-e-A’zam رَضِىَ اللّٰەُ عَنْهُ also include ‘sharing of produce’ i.e., Mazar’at [مزارعت]. It is stated in the Sahih Bukhari: He رَضِىَ اللّٰەُ عَنْهُ entered into agreement of ‘sharing of produce’ with people in this way that when he رَضِىَ اللّٰەُ عَنْهُ would bring the seeds himself, he would get half share of the produce of land and if they bring the seeds, they would get so-and-so amount of produce. (Sahih Bukhari, vol. 2, pp. 87, Hadees 2327)
Moreover, leather business was also the source of income of Sayyiduna ‘Umar Farooq رَضِىَ اللّٰەُ عَنْهُ. It is stated in a -Hanafi Fiqh book ‘Ikhtiyar Sharh-e-Mukhtar’: ‘عُمَرُ يَعْمَلُ فِی الْأَدِيْمِ’ i.e. Sayyiduna ‘Umar Farooq رَضِىَ اللّٰەُ عَنْهُ used to do leather business. (Al-Ikhtiyar-it-Ta’leel-il-Mukhtar, vol. 2, pp. 182, part 4)
In his childhood, Sayyiduna ‘Umar Farooq رَضِىَ اللّٰەُ عَنْهُ also used to graze his father’s camels and when he grew up a little, he started grazing the camels of the tribe ‘Bani Makhzoom’ along with his father’s camels. Once he رَضِىَ اللّٰەُ عَنْهُ passed by the place of grazing of his camels, he رَضِىَ اللّٰەُ عَنْهُ said, ‘I used to graze my father’s camels in this very valley.’ (Al-Istee’aab, vol. 3, pp. 243; Faizan Farooq-e-A’zam, vol. 1, pp. 66)
Business trips of Sayyiduna ‘Umar Farooq
Authentic history and tourism books hardly bring any piece of information about the business trips of Sayyiduna ‘Umar Farooq رَضِىَ اللّٰەُ عَنْهُ. In the book, Ansaab-ul-Ashraaf ‘Allamah Balazuri [بَلاذُری] has mentioned only one mercantile caravan of Sayyiduna ‘Umar Farooq رَضِىَ اللّٰەُ عَنْهُ leaving for Syria. (Ansaab-ul-Ashraaf, vol. 10, pp. 315)
