Verse [ 106:2] رِ‌حْلَةَ الشِّتَاءِ وَالصَّيْفِ (...their familiarity with the trips of winter and summer.) It is a known fact that Makkah is situated in an utterly bleak and arid valley where no agricultural produce grows, nor are there any orchards where the people of Makkah could reap any kind of fruits. Therefore, the founder of the House of Allah, Sayyidna Ibrahim Khalil ullah (علیہ السلام) prayed to Allah at the time of founding the city, thus: [ 2:126] رَ‌بِّ اجْعَلْ هَـٰذَا بَلَدًا آمِنًا وَارْ‌زُقْ أَهْلَهُ مِنَ الثَّمَرَ‌اتِ (My Lord, make this a city of peace, and provide its people with fruits) and this fact is mentioned in [ 28:57], thus: يُجْبَىٰ إِلَيْهِ ثَمَرَ‌اتُ كُلِّ شَيْءٍ (to which the fruits of everything are drawn) ". The Quraish thus needed to make these commercial trips out of Makkah into the neighboring territories to bring the necessities of life to their city. Sayyidna Ibn ` Abbas ؓ reports that the people of Makkah were in a state of abject poverty and Hashim, the great grandfather of the Prophet ﷺ ، exhorted the Quraish to undertake the trading caravans to the neighboring territories. As Syria was a cold region, they went there in summer; and Yemen had a warm climate, so they went there in winter to carry out their commercial activities. They, after their commercial ventures that brought to them great profits and gains, would return to their city safely due to the respect that the people had for them, because they were the keepers and custodians of Allah's sanctuary. Therefore, whoever knew them would honor them. Even those who came to them and traveled with them, would be safe because of them. Hashim was the leader of the Quraish and maintained the economic principle to distribute among the rich and the poor members of the Quraish the gains and the profits made in their business. As a result, even the poor people lived like the wealthy people. Furthermore, an additional Divine favor was granted to them: Allah spared them the trouble of making these annual trips, in that the areas adjacent to Makkah such as Yemen, Tabalah and Harsh were made fertile, fecund and productive where corns, food grains and other agricultural produce grew abundantly - even more than their need. As a result, they had to carry these agricultural produce to Jeddah where they sold them. Thus most of the necessities were available in Jeddah. The people of Makkah, instead of undertaking the two long journeys, went to Jeddah, merely two stations away, to bring their necessities of life. In the current verse, Allah mentions His favor upon them.
