[17].Surah Al-Isra' [The Journey By Night]: Ayat 34-35

 also known as Surah Bani Israel [The Children of Israel]

Ayat 34. And come not near to the orphan's property except to improve it, until he attains the age of full strength. And fulfil (every) covenant. Verily! the covenant, will be questioned about.
Ayat 35. And give full measure when you measure, and weigh with a balance that is straight. That is good (advantageous) and better in the end. 

Hazrat Abu Shuraih Khuwailid bin `Amr Al-Khuza`i (May Allah be pleased with him) reported: The Messenger of Allah [SAWW](PBUH)  said, "O Allah, I declare inviolable the rights of two weak ones: the orphans and women".

[Sunan' An-Nasa'i](Arabic: سنن النسائي )]

Lesson : as mentioned above in Surah Al-Isra Ayat 34. "come not near to the orphan's property except to improve it" The poor are generally treated callously in human society. Women and orphans are regular victims of this cruelty. They are deprived of their share in property to which they are entitled under the Islamic law. In some cases their properties are usurped and they are maltreated at the hands of usurpers. The Prophet (PBUH) has threatened them with serious consequences to prevent the Muslims from committing such injustice. The attitude of Muslims and the teachings of Islam in this matter are two different things. How can Islam be blamed for the attitude of Muslims? It is time Muslims should understand that Islam is getting a bad name because of their bad conduct. As a result of this they are committing a double crime. On the one hand, they are guilty of usurping others of their legitimate rights and perpetrating cruelties, and on the other, disgracing their religion. In other words, rather than preaching Islam they are creating obstacles in the way of people joining the fold of Islam. May Allah grant us guidance to follow the right path. Amin!
