61. Surah As-Saff (The Row or the Rank)
The Rashidite Caliphate, is the collective term comprising the first four caliphs—the “Rightly Guided” or Rashidun caliphs—in Islamic history and was founded after Muhammad’s death in 632.
After Muhammad’s death in 632, the Medinan Ansar debated which of them should succeed him in running the affairs of the Muslims while Muhammad’s household was busy with his burial. Umar (a Quraish) and Abu Ubaidah ibn al-Jarrah pledged their loyalty to Abu Bakr, with the Ansar and the Quraish soon following suit. Abu Bakr thus became the first Khalifa Rasul Allah (Successor of the Messenger of God), and embarked on campaigns to propagate Islam. First, though, he would have to subdue the Arabian tribes which had gone back on their oaths of allegiance to Islam and the Islamic community. As a Khalifa or caliph he was not a monarch and never claimed such a title nor did his three successors do so.
in the poem the wind, the poet describes the power of the wind. when he sees the kites flying high in the sky and also the birds soaring high, he knows the wind is doing its job. The poet cannot see the wind but when it blows past him he knows that it is at work. so with the childish curiosity, the poet wants to know what kind of person the wind is like. whether it is young or old, is it a beast or a tree or just a small child like himself, but a little stronger.
