In the 2nd year (624 AD) after Hijra (migration) the Prophet (saws) received some gifts of homage from the Negus, King of Abyssinia. A signet ring, a pair of shoes and an ‘anaza (a short spear), and Bilal ibn Rabah (raa) was given the honour to walk infront of the Prophet (saws) on his way to Salat al-Eid and Salat-Istisqa (prayer for rain) carrying the spear.
Upon reaching the Musalla, Bilal Al-Habashi (the Abyssinia) (raa) would pitch the spear in the ground one or two yards infront of the Prophet (saws) saws.
The Two Festivals (Eids)
Bukhari :: Book 2 :: Volume 15 :: Hadith 89
Narrated Ibn Umar (raa): On the day of ‘Id-ul-Fitr and ‘Id-ul-Adha a spear used to be planted in front of the Prophet (saws) (as a Sutra for the prayer) and then he would pray.
Thus Bilal (raa), along with being the first muazzin of Islam had the honor of keeping the Prophets spear throughout his lifetime.
Call to Prayers (Adhaan)
Bukhari :: Book 1 :: Volume 11 :: Hadith 606
Narrated ‘Aun bin Abi Juhaifa:
My father said, "I saw Allah’s Apostle (saws) at a place called Al-Abtah. Bilal (raa) came and informed him about the prayer and then came out with an Anza and planted it in front of Allah’s Apostle (saws) at Al-Abtah and pronounced the Iqama."

Death of The Prophet, Fatima’s Dua’ For Her Father
Narrated Anas (raa): When the ailment of the Prophet (saws) got aggravated, he became unconscious whereupon Fatima (raa) said, “Oh, how distressed my father is!”
He said, “Your father will have no more distress after today.”
When he expired, she said, “O Father (saws)! Who has responded to the call of the Lord Who has invited him! O Father (saws), whose dwelling place is the Garden of Paradise (i.e. Al-Firdaus)! O Father! We convey this news (of your death) to Gabriel.”
When he was buried, Fatima (raa) said, “O Anas (raa)! Do you feel pleased to throw earth over Allah’s Apostle (saws)?”

Patience & Perseverance
Riyadh as-Saaliheen (The Gardens of the Righteous), by Imam an-Nawawi
This Hadith shows that it is permissible to express the trouble and restlessness which one feels at the time of death. Similarly, expression of pain and grief in a natural way in the event of someone’s death is also permissible.
To remember the virtues of the deceased is also permitted but it is to be free from wailing and moaning, lamentation and crying, and tearing off clothes, etc. The last words of Fatimah (raa) are also a way of expressing grief and sadness and not a criticism on the burial of the Prophet (saws) because such criticism is prohibited by Shari’ah and no one is exempted from it.
