Explanation:
1:
Musaylimah the Liar,
Aswad al-Ansi,
Sajah,
Baha’ullah,
Babullah,
and Mirza Ghulam Ahmad Qadiani are among these liars.

Benefits and Issues:
By this enumeration are meant those well-known claimants to prophethood whose cases became famous, such as Musaylimah al-Kadhdhab, Aswad al-Ansi, Tulayhah ibn Khuwaylid, Sajah al-Tamimiyyah, Mukhtar ibn Ubayd al-Thaqafi, Harith al-Kadhdhab during the era of Abd al-Malik ibn Marwan, and besides these, who knows how many others there have been.
Mirza Ghulam Ahmad Qadiani, who appeared in India, was also a person of this same category, that is, a false dajjal.

Explanation of the Hadith:
The meaning of this noble hadith is that before the Day of Judgment, nearly thirty (30) false prophets and great liars (dajjal) will appear. In another hadith, twenty-seven liars are mentioned. Thus, it is narrated from Sayyiduna Hudhayfah radi Allahu anhu that indeed the Prophet of Allah sallallahu alayhi wa sallam said:
«فِىْ اُمَّتِى كَذَّابُوْنَ وَدَجَّالُوْنَ سَبْعَةٌ وَّعِشْرُوْنَ ، مِنْهُمْ اَرْبَعُ نِسْوَةٍ ، وَاِنِّىْ خَاتَمُ النَّبِيِّيْنَ لَا نَبِىَّ بَعْدِىْ .» [مسند احمد: 396/5 ، رقم: 23358 - معجم كبير، للطبراني، رقم: 3029 - معجم اوسط، للطبراني، رقم: 5446 - شرح مشكل الآثار، للطحاوي، رقم: 2953]
Shaykh Shu'ayb has graded it as "sahih" (authentic).
"There will appear twenty-seven liars and dajjals in my ummah. Four of them will be women. Whereas I am the last Prophet. There is no Prophet after me."
Similarly, in another hadith, seventy are also mentioned. The Messenger of Allah sallallahu alayhi wa sallam said:
«لَا تَقُوْمُ السَّاعَةُ حَتّٰى يَخْرُجَ سَبْعُوْنَ كَذَّابًا» [مجمع الزوائد، كتاب الفتن: 454/7 ، رقم: 12490 - فتح الباري: 13/ 76 ، 115]
"The Hour will not be established until seventy liars have appeared."
These hadiths can be reconciled in such a way that mentioning these numbers is an indication of the abundance of the emergence of such liars. It is also a principle that "specifying a number does not negate the possibility of more."
In accordance with these hadiths, many liars and dajjals have appeared on this pure land and, through their schemes, have continued to mislead the Muslim ummah. The history of Islam shows that the emergence of false prophets began in the very era of the Prophet sallallahu alayhi wa sallam. Thus, Musaylimah the Liar claimed prophethood in Yamamah, and Aswad al-Ansi did so in Yemen. Accordingly, it is narrated in a hadith from Abdullah ibn Zubayr radi Allahu anhu:
«لَا تَقُوْمُ السَّاعَةُ حَتّٰى يَخْرُجَ ثَلَاثُوْنَ كَذَّابًا مِنْهُمْ: مُسَيْلَمَةُ، وَالْعَنْسِىْ، وَالْمُخْتَارُ» [مسند أبي يعلي۔ كنزالعمال، رقم: 38374 - فتح الباري: 754/6]
Hafiz Ibn Hajar has graded it as "hasan" (good).
"The Hour will not be established until nearly thirty liars have appeared; among them are Musaylimah, Aswad al-Ansi, and Mukhtar."
Furthermore, during the caliphate of Abu Bakr as-Siddiq, Tulayhah ibn Khuwaylid al-Asadi claimed prophethood among Banu Asad ibn Khuzaymah, and Sajah at-Tamimiyyah did so among Banu Tamim. After that, from time to time, many vile, despicable, and ignoble people committed this grave crime.
It should be noted that among these liars are also Mirza Ghulam Ahmad Qadiani, the founder of Qadianism; Nur Muhammad Atki, the founder of Zakiriyyah; Baha'u'llah Irani, the founder of Baha'ism; and Gohar Shahi of Kotri, who, by claiming prophethood and messengership, led a great multitude astray. «اللهم اهدهم.»
Among all of them, the last will be the one-eyed Dajjal, who, along with claiming prophethood, will also claim divinity. The Messenger of Allah sallallahu alayhi wa sallam said:
«وَاِنَّهُ وَاللّهِ! لَا تَقُوْمُ السَّاعَةُ حَتّٰى يَخْرُجَ ثَلَاثُوْنَ كَذَّابًا آخِرُهُمْ الْاَعوَرُ الدَّجَّالُ .» [مسند احمد: 16/5 - صحيح ابن خزيمه: 1/ 682 ، 683 ، 1397 - مستدرك حاكم: 329/1 - صحيح ابن حبان، رقم: 2852]
Ibn Hibban, Ibn Khuzaymah, and al-Hakim have graded it as "sahih" (authentic).
"The Hour will not be established until thirty liars have appeared; the last of them will be the one-eyed Dajjal."
