Prophet Muhammad (s.a.a.w.) lived a life of poverty from the day he was born till the day he died. Whenever, he had anything valuable, be it food, money, gold, or sheep, he preferred to give all away, even when he and his family were in need.
In an agreed upon hadeeth, the Prophet (s.a.a.w.) said, "If I had as much gold as the weight of Uhud, it would not please me to have a single dinar out of it with me after the passage of three days, but I would hold back something for the repayment of a debt. I would distribute it among the slaves of Allah like this and like this and like this.'' And he (PBUH) pointed in front of him, and on his right side and on his left side. We then walked a little further and he (PBUH) said: "The rich would be poor on the Day of Resurrection, except he who spent like this and like this and like this,". and he pointed as he did the first time. "But such persons are few".
Prophet Muhammad (pbuh) not only preached to the people to show kindness to each other but also to all living souls. He forbade the practice of cutting tails and manes of horses, of branding animals at any soft spot, and of keeping horses saddled unnecessarily. [Sahih Muslim] If he saw any animal over-loaded or Milad he would pull up the owner and say,
"Fear Allah in your treatment of animals." [Abu Dawood]
A companion came to him with the young ones of a bird in his sheet and said that the mother bird had hovered over them all along. He was directed to replace her offspring in the same bush (Mishkat, Abu Dawood)
During a journey, somebody picked up some birds eggs. The bird's painful note and fluttering attracted the attention of the Prophet (pbuh), who asked the man to replace the eggs. [Sahih Bukhari]
As his army marched towards Makkah to conquer it, they passed a female dog with puppies. The Prophet (pbuh) not only gave orders that they should not be disturbed, but posted a man to see that this was done.
He stated, "Verily, there is heavenly reward for every act of kindness done to a living animal."
Fourteen hundred years ago, the polytheists and Jews in Arabia asked Prophet Muhammad (s.a.a.w.) questions about God. Some of these questions were:
Tell us of your Lord's ancestery. O Muhammad, tell us attributes of your Lord, who has sent you as prophet. What is your Lord made of? Is He made of gold, silver, iron or what? Does He belong to a race of Gods? Does He have parents or children? Who will inherit the earth after Him?
The answer came in the following verse of the Holy Quran:
قُلْ هُوَ اللَّهُ أَحَدٌ
Say: "He is Allah, the One and Only.” (The Holy Quran, Surah Al-Ikhlas, Ayah 1, 112:1)
Let us first analyze the sentence, “ Huwa-Allahu Ahad”, هُوَ ٱللَّهُ أَحَدٌ lexically.
In this sentence, Huwa is the subject (mubtada) and Allahu its predicate (its khabar), and Ahad-un its second predicate (second khabar). According to this parsing the sentence means: "He (about Whom you are questioning me) is Allah, the One and Only.” Another meaning according to the language rules can be, "He is AIIah, the One."
(2:83) Remember that We made a solemn covenant with the children of Israel to this effect: worship none save Allah: be good to your parents, to your relatives, to the orphans and to the helpless; speak aright with the people: establish the Salat and pay the Zakat. But with the exception of a few, you all slid back from it and are paying no heed to it even now.
