And Matar Waraq said that there is no harm in it, and its mention is in the Noble Qur’an; it is, in any case, the truth. After that, he recited this verse (from Surah An-Nahl) «وترى الفلك مواخر فيه ولتبتغوا من فضله‏» :“And you see the ships cleaving through it (the sea), that you may seek of His bounty.”In this verse, the word «فلك» is used in the meaning of ‘ship’; this word is used in the same way for both singular and plural. Mujahid (may Allah have mercy on him) said (in the explanation of this verse) that the ships cleave through the wind, and the ships that are large are the ones that clearly cleave through the wind (to the observer).

Abu Hurairah (ra) said, "Allah's Messenger (saws) mentioned a person from Bani Israel who travelled by sea and carried out his needs." Then he narrated the whole story. (See Hadith no. 2291)

And in Surah An-Nur, the statement of Allah, the Blessed and Exalted: «جال لا تلهيهم تجارة ولا بيع عن ذكر الله‏» "Those men whom neither trade nor sale distracts from the remembrance of Allah." Qatadah said that the noble Companions, may Allah be pleased with them, used to engage in trade. But whenever any obligation from Allah came before them, their trade and business could not distract them from the remembrance of Allah until they had fulfilled the obligation of Allah.

Narrated Jabir: A caravan arrived (at Medina) while we were offering the Jumua prayer with the Prophet. The people left out for the caravan, with the exception of twelve persons. Then this Verse was revealed: 'But when they see some bargain or some amusement, they disperse headlong to it and leave you standing." (62.11)

Narrated `Aisha: The Prophet said, "If a woman gives in charity from her house meals without wasting (i.e. being extravagant), she will get the reward for her giving, and her husband will also get the reward for his earning and the storekeeper will also get a similar reward. The acquisition of the reward of none of them will reduce the reward of the others."

Narrated Abu Huraira: The Prophet said, "If a woman gives something (i.e. in charity) from her husband's earnings without his permission, she will get half his reward."

Narrated Anas bin Malik: I heard Allah's Apostle saying, "whoever desires an expansion in his sustenance and age, should keep good relations with his Kith and kin."

Narrated `Aisha: The Prophet purchased food grains from a Jew on credit and mortgaged his iron armor to him.

Narrated Qatada: Anas went to the Prophet with barley bread having some dissolved fat on it. The Prophet had mortgaged his armor to a Jew in Medina and took from him some barley for his family. Anas heard him saying, "The household of Muhammad did not possess even a single Sa of wheat or food grains for the evening meal, although he has nine wives to look after." (See Hadith No. 685)

Narrated `Aisha: When Abu Bakr As-Siddiq was chosen Caliph, he said, "My people know that my profession was not incapable of providing substance to my family. And as I will be busy serving the Muslim nation, my family will eat from the National Treasury of Muslims, and I will practice the profession of serving the Muslims."
