﴿ إِۦلَٰفِهِمْ رِحْلَةَ ٱلشِّتَآءِ وَٱلصَّيْفِ ﴾

“secure in their winter and summer journeys,”

(For their taming (We cause)) as We have tamed (the caravans to set forth in winter and summer) the caravans to set forth in winter to Yemen and in summer to Historic Syria; it is also said that this means: belief in Allah's divine Oneness is not hard for Quraysh just as their winter and summer trips are not hard for them.
