Hadith

Reward is a translation of Hasanah حَسَنَة which is the reward granted by Allah to pious on doing good deed. The size and amount of the reward is very great which can be more than all the bounties of this world. Every good deed will make you gain ten times the reward of it as Allah says in Quran (Sura 6, verse 160).

Reciting every letter in Quran will bring ten rewards as it is mentioned in authentic Hadeeth. (al-Kaafi 2:448).

Wassalam.

This authentic Hadeeth ذِكرُ عليّ عبادة is narrated in Shia books and Sunni books. Shia books like:

1. Manla Yahdharuhul Faqeeh; Hadeeth number 2145 and 2146

2. Kashful Yaqeen 449.

3. Al-Siratul Mustaqeem, V.1, P. 209.

4. Al-Ekhtisaas as quoted in Biharul Anwaar , V. 91, P. 69.

'Sunni books narrated this Hadeeth from many companions and from 'Aisha saying the she heard Rasoolullah (SAWA) saying: Remembering (mentioning) Ali is a worship.

1. It is narrated by al-Khawarizmi in al-Manaaqib 261.

2. Ibn al-Maghazili in al-Manaaqib, Hadeeth 243.

3. Ibn 'Asaakir in Tareekh Dimishq, V. 42, P. 356.

4. Al-Wissabi in Asnal Mataalib , page 76.

Allama Mohammad Baqir al-Majlisi is a great scholar in the Hadeeth sciences and he compiled the well known collection of Hadeeth in his famous book Biharul Anwaar. He has written others books as well. His grading is according to his own research and Ejtihaad. Other scholars have their grading which can be like or different from his grading as all the Mujahid scholars are free in their research in the narrators and narrations.

Al-Kaafi book has the most authentic collection of narrations of Hadeeth but we don't say that every narration in al-Kaafi is equally authentic. The expert scholars have their right to study and verify every narration.

Yes. In the most authentic books of Hadeeth known as Al-Tahtheeb by Al-Shaikh Al-Toosi, volume 3, page 81, there is an authentic Hadeeth narrated by Hammaad ibn Easa. This Hadeeth has the procedure of Salaat from Takbeer to Salaam in a single narrative.

Wassalam.

I did not find any authentic Hadeeth in Shia books of Hadeeth suggesting that most of Dajjal's followers will be women. It is narrated in many Sunni books e.g. Musnad Ahmad Ibn Hanbal from Abdullah Ibn Omar.

Wassalam.

1. Both Shia and Sunni scholars emphasised on the authenticity of all the narrators of every Hadeeth, but they differ when they come across some narrators who are controversial e.g. Abu Huraira, Samarah Ibn Jundob, etc who are considered as accepted by many Sunnis while not accepted by Shia scholars because of their behaviour against Ahlul Bayt(AS).
2. Shia scholars follow the most strict procedure of authentication of every narrator whether Shia or Sunni.

3. Shia scholars take Ahlul Bayt as the main source of the authentic Hadeeths from the Prophet (SAWA) not only because they are the most pious and most knowledgeable about the Real Sunnah of the Prophet (SAWA) as they lived with him, but also because of the order of the Prophet (SAWA) to all Muslims to keep following Quran and Ahlul Bayt (SAWA) (Saheeh Muslim, Hadeeth number 4425, and Tirmithi; Hadeeth number 3718 and 3720, and al-Mustadrak by Al-Haakim al-Nisabori; Hadeeth number 4576 and hundreds of other Sunni and Shia books.
4. Shia scholars have written the Hadeeths right from the time of Prophet Muhammad (SAWA) and through the times of all the Infallible Imams (AS), while Sunni scholars were forbidden by their rulers from writing any Prophetic Hadeeth from the time of Saqeefa till the time of Umar ibn Abdul Azeez who was first Sunni ruler who lifted tha ban on writing Hadeeths, which means that Sunni scholars did not write Hadeeths for around hundred years. That has definitely affected the authenticity and the accuracy of their narrations.

5. Sunni rulers used to interfere in religion to suit their political aims. Mu'awiyah for example used to pay huge amounts of money to some narrators to fabricate narrations in his favour and against Ahlul Bayt (AS). He used to kill or torture scholars who narrate any Hadeeth in favour of Imam Ali (AS). This corruption went on during tyrant governments of Bani Umayyad and Bani Abbas. Shia Hadeeths since beginning till now are pure from any political corruption.

6. Shia scholars following the teachings of Ahlul Bayt(AS) do not accept any narration which contradicts Quran, while you find many Sunni scholars narrate narration which are clearly against Quranic verses and claim than authentic narration is accepted even if it contradicts a Quranic verse. For details you may see ( A review of the two Saheeh ( Bukhari and Muslim) by Shaikh Sadiq Najmi and ( (Quick look at the two Saheehs, by Shaikh Aasif Mohsini and many other books in this subject).

7. Many Sunni books narrated from open enemies of Ahlul Bayt and considered their narrations as authentic. Bukhari narrated from Imran Ibn Hattaan who used to praise Ibn Muljam, the murderer of Imam Ali (AS), and also from Uthman ibn Hareez who used to openly curse Imam Ali every day. This shows that some non trusted narrators have penetrated in some Sunni books and taken as trusted narrators. This has added to the difference between Muslims.

Wassalam.

There are many narrations in Sunni and Shia books regarding the 73 sects, but most of the narrations have additions which are not authentic especially what is in some Sunni books that the saved sect will be those who follow me and my companions ما أنا عليه وأصحابي. Leading Sunni Ulama stated that this narration is fabricated.

Our Shia Ulama narrated many narrations about the 73 sects as find in Bisharat Al-Mustafa narrated from Ameerul Mo'mineen (AS) which states that saved sect will be those who follow the real successor of the Prophet (SAWA).

This narration does not mean that all Muslim sects will be in hellfire except one sect, but means that there will be right sect despite of the different sects. The followers of the right sect will be saved because there have obeyed the orders of Allah (SWT) and the Prophet (SAWA).

Wassalam.
