Fairness of Hazrat Umar bin Al Khattab R.A

Narrated Ibn Umar, who was son of Khalifa Umar ibn Al Khattab:
Umar bin Al-Khattab fixed a grant of 4000 (Dirhams) for every Early Emigrant (i.e. Muhajir) and fixed a grant of 3500 (Dirhams) only for Ibn ‘Umar. Somebody said to ‘Umar, “Ibn ‘Umar is also one of the Early Emigrants; why do you give him less than four-thousand?” ‘Umar replied, “His parents took him with them when they migrated, so he was not like the one who had migrated by himself. Shaih Bukhari (5:58:251)
Umar b. al-Khattab was not afraid of criticism. Once gave a public sermon in which he asked the congregation to refrain from fixing heavy mahrs, and stated that the Prophet had declared no-one should give more than 400 dirhams. A woman immediately stood up and challenged him, quoting the verse 4:20 from the Qur’an: ‘But if you decide to take a wife in place of another, even if you had given the first a heap of gold (quintar) for a dowry, you shall not take the least bit back.’ Umar went back to the minbar and withdrew his words stating ‘the woman is right, and Umar is wrong. Whoever wishes may give as much property as he wishes to give.’ (Ibn Hajar al-Athqalani, Fath al-Bari, 9:167).

Hazrat Abu Ayyub al-Ansari R.A

Abu Bakr, may God be pleased with him, once left his house in the burning heat of the midday sun and went to the mosque. Umar saw him and asked, “Abu Bakr, what has brought you out at this hour? Abu Bakr said he had left his house because he was terribly hungry and Umar said that he had left his house for the same reason. The Prophet came up to them and asked, “What has brought the two of you out at this hour?” They told him and he said, “By Him in Whose hands is my soul, only hunger has caused me to come out also. But come with me.”
They went to the house of Abu Ayyub al-Ansari. His wife opened the door and said, “Welcome to the Prophet and whoever is with him.”
“Where is Abu Ayyub?” asked the Prophet. Abu Ayyub, who was working in a nearby palm grove, heard the Prophet’s voice and came hurriedly.
“Welcome to the Prophet and whoever is with him,” he said 
Abu Ayyub went out and cut a cluster of dates in which there were ripe and halfripe dates. “I did not want you to eat this,” said the Prophet. “Could you not have brought only the ripe dates?” “O Rasulullah, please eat from both the ripe dates (rutb) and the half ripe (busr). I shall slaughter an animal for you also. ” “If you are going to, then do not kill one that gives milk,” cautioned the Prophet. Abu Ayyub killed a young goat, cooked half and grilled the other half. He also asked his wife to bake, because she baked better he said.
When the food was ready, it was placed before the Prophet and his two companions. The Prophet took a piece of meat and placed it in a loaf and said, “Abu Ayyub, take this to Fatima. She has not tasted the like of this for days.
When they had eaten and were satisfied, the Prophet said reflectively: “Bread and meat and busr and rutb!” Tears began to flow from his eyes as he continued:

“This is a bountiful blessing about which you will be asked on the Day of judgment. If such comes your way, put your hands to it and say, Bismillah (In the name of God) and when you have finished say, Al hamdu lillah alladhee huwa ashbana wa anama alayna (Praise be to God Who has given us enough and Who has bestowed his bounty on us). This is best.”

Hazrat Abdullah ibn Abbas R.A

Abdullah was the son of Abbas R.A, an uncle of the noble Prophet. He was born just three years before the Hijrah. When the Prophet SAWW died, Abdullah R.A was thus only thirteen years old.
It was not only in the collection of hadith that Abdullah R.A specialized. He devoted himself to acquiring knowledge in a wide variety of fields. He had a special admiration for persons like Zayd ibn Thabit R.A, the recorder of the revelation, the leading judge and jurist consult in Madinah, an expert in the laws of inheritance and in reading the Quran. When Zayd R.A intended to go on a trip, the young Abdullah R.A would stand humbly at his side and taking hold of the reins of his mount would adopt the attitude of a humble servant in the presence of his master. Zayd R.A would say to him: “Don’t, O cousin of the Prophet.” “Thus we were commanded to treat the learned ones among us,” Abdullah R.A would say. “And Zayd R.A would say to him in turn: “Let me see your hand.” Abdullah R.A would stretch out his hand. Zayd R.A, taking it, would kiss it and say: “Thus we were commanded to treat the ahl al-bayt members of the household of the Prophet SAWW.”
Abdullah ibn Abbas R.A was constant in his devotions. He kept voluntary fasts regularly and often stayed up at night in Prayer. He would weep while praying and reading the Quran. And when reciting verses dealing with death, resurrection and the life hereafter his voice would be heavy from deep sobbing.
