Helping weak and needy non-Muslims
Almighty Allah has made the Holy Prophet (Sallallahu alaihi wa sallam) very gentle, affectionate and benevolent. Those laudable attributes of the Holy Prophet (Sallallahu alaihi wa sallam) which were described by Hadhrat Khadija Kubra (May Allah be well pleased with her) are:
إِنَّكَ لَتَصِلُ الرَّحِمَ ، وَتَحْمِلُ الْكَلَّ ، وَتَكْسِبُ الْمَعْدُومَ ، وَتَقْرِى الضَّيْفَ ، وَتُعِينُ عَلَى نَوَائِبِ الْحَقِّ
Translation: You maintain good relations with relatives, i.e. you fulfill the rights of the relatives. You share the burden of the weak i.e. you take the burden of old, handicapped, weak non-Muslims on yourself. You share your income with the needy and the poor. You host guests and help those needy people who are on the path of truth.
This is about the time when all those who lived in that society were non-Muslim. The Holy Prophet (Sallallahu alaihi wa sallam) had not yet declared His Prophethood. He treated relatives nicely, financially helped the poor and the needy, hosted guests, helped people in difficulties. Who were all these people? All of them were non-Muslim. This obviates that the Holy Prophet (Sallallahu alaihi wa sallam) treated non-Muslims with affection and helped them in their times of need.
This shows Muslims that they should treat their non-Muslim relatives nicely. They should help those non-Muslims who are in need. They should host non-Muslim guests and should help those non-Muslims who are facing difficulties.
