"[And they bear your heavy loads], meaning: camels and cattle, [to a land you could not have reached except with difficulty to yourselves]. He says: Were it not for the fact that they carry your heavy loads to the land you desire, you would not have been able to reach that land except with hardship upon yourselves. [Indeed, your Lord is Kind and Merciful]. He says: It is through the kindness of Allah and His mercy that He subjected these livestock for you; and for the disbeliever, it is the mercy of this world, so that He may provide him therein with blessings."
