Buy things responsibly; Fulfill your obligations with integrity & sincerity; Be honest & trustworthy when engaging in transactions or agreements; Do not take more than you can handle financially.

This hadith highlights the importance of financial responsibility in Islam. It is narrated that the Prophet Muhammad, peace be upon him, bought some food from a Jew on credit and gave him his shield as collateral. This shows us that it is permissible to buy something on credit if one has the intention to pay back what they owe. However, it also teaches us that we should not take more than we can handle financially and should only borrow what we are able to pay back with ease. Furthermore, this hadith also emphasizes the importance of honesty and trustworthiness when engaging in any kind of transaction or agreement; even if it is just buying food on credit, one must still fulfill their obligations with integrity and sincerity.
