`Umar b. al-Khattab

It is untrue. Imam Ali (AS) never gave any of his sons the  name of Umar Ibn Khattab.

We have narrations that one of his sons was called Amr عمرو not Umar عمر . Amr عمرو  is a different name.

1. Hadeeth 2408 in Saheeh Muslim is authentic according to main Sunni scholars of Hadeeth like Shu'aib al-Arna'oot who stared and confirmed that this Hadeeth is Saheeh ( Authentic) (Takhreej al-Musnad, 17 /170). This Hadeeth is narrated in many other Sunni books of Hadeeth and states the order of the Prophet (SAWA) to follow Quran and Ahlul Bayt (AS) to be on the right path of Islam, but it was been ignored by many Muslims because of political reasons.

2. Hadeeth 3175 in Saheeh Muslim is narrated from Ayesha and it claims that the Prophet Muhammad (SAWA) was inflicted by black magic. This is against Quran which stated that the Prophet is protected by Allah. This false claim is same the enemies of the Prophet said to the believers (You are following a man who has been inflicted by black magic. (Sura Al-Furqan, verse 8).

No doubt, this narration is false and can never be true.

Wassalam.

The narration claiming that the Prophet Muhammad (SAWA) was bewitched is definitely false allegation on the Prophet. You read in Sura Furqan, verse 8 : : The wrongdoers say (to the believers) : You are following non but a bewitched man.

'This is a clear evidence against this false allegation.

Umar contradicting the Prophet (SAWA) has been narrated in many authentic narrations in Sunni books.

Wassalam.

Islam did not come to force people to believe in it. Allah Says in Quran: The is compulsion in religion. (Sura 2, verse 256).

The Prophet Muhammad (SAWA) did not initiate wars on people to force the on Islam.

Wars during the government of Saqeefah rules were mostly politically motivated.

'Wassalam.

Followers of Umar have removed every evidence which proves that folding hands was ordered by him and claimed that it was done by the Prophet but they failed in presenting any authentic Hadeeth to support their claim. Muslims of Madina used to pray without folding their hands. Malik bin Anas the founder of Sunni Maliki sect clearly mentioned that the Salaah should be with opening hands and not folding them.The narration in Bukhari on this subject is from Sahl ibn Sa'd never said that the Prophet ever folded his hands in Salaah but states that people were been ordered to fold their hands. The narration was made after the order of Umar to fold hands in Salaah. 

No one knows the real Sunnah of the Prophet (SAWS) more than Ameerul Mo'mineen Ali (AS) who was against folding the hands and clearly ordering Muslims not to fold their hands in Salaah because it is a practise of the Zoroastrian and Jews.Wassalam 

This claim is not true at all. It is part of the politically oriented fabricated narrations. Even leading Sunni scholars said that the narration is fabricated.

‘Keep in mind that lot of narrations in praise of the Saqeefah rulers were fabricated for political reasons. This fact is well known to the scholars of Muslim history and science of Hadeeth.

Wassalam.

Imam Ali (AS) has removed the deviations which were created by the previous three rulers of Saqeefah as he clearly declared that they have deliberately changed the Sunnah of the Prophet (SAWA). He removed the discrimination between Arabs againt non Arab Muslims and between Quraish tribe against other tribes etc.

Imam Ali (AS) suffered a lot from the hypocrites and Quraish tribe who were against him and against his reforms. They took the name of Umar as a slogan against Imam Ali (AS). They asked him in the month of Ramadan to appoint for them a person to lead Taraweeh. He clearly said that it is a Bid'ah away from the Sunnah of the Prophet. They insisted and gathered in the Masjid of Kufa. He sent his son Imam Al-Hasan (AS) to stop them from Taraweeh, but they shouted loudly ( WA SUNNATA UMARAAH)(Where is the Sunnah of Umar?). It reached to a critical point of civil disorder among Muslim society. Imam Ali (AS) had no choice but to leave them to do what they want to save the Muslims from turmoil. You can find details in Sunni books like Sharh Al-Nahj by Ibn Abi Al-Hadeed , V. 12, P. 283 and Tareekh Al-Tabari V.4, From page 281 onward.

Shia books like Wasaa'il Al-Shia , V.5 P. 193 has also mentioned some details of    this matter.

Wassalam.

Umar ibn Al-Khattab is different from Umar ibn Sa'ad. Umar ibn Al-Khattab is the second ruler of Saqeefah after Abu Bakr. Umar Ibn Sa'ad is the leader of the army of Yazeed who killed Imam Husain (AS) and his companions in Karbala.

Wassalam.

Yes. Hijri (Islamic) calender never started from Muharram because Hijra of the Prophet (SAWA) started in Rabiul Awwal and not in Muharram. Muharram was the start of the year of pagan Arabs before Islam. Umar ibn Al-Khattar was the first who brought it among Muslims.

Wassalam.

Islam does not force people to believe in it. No compulsion in religion. Majority of people in Iran embraced Islam willingly when they saw the great teachings of IIslam. Many Zoroastrians remained in their inherited faith till today. No one has forced any one to become a Muslim.
