This dua اللَّهُمَّ بَارِكْ لَنَا فِي رَجَب، وَشَعْبَانَ، وَبَلِّغْنَا رَمَضَانَ
There is no saheeh hadeeth from the Prophet that speaks of the virtues of the month of Rajab. But Rajab of sacred 4 months. But such dua is from daeef (weak narration )as related by many Scholars. So it is better to avoid such dua which is not from sunnah.
Ibn ‘Uthaymeen (may Allah have mercy on him) said: There is no saheeh hadeeth that speaks of the virtues of Rajab. The month of Rajab is no different from the month of Jumaada al-Aakhirah that comes before it, except that it is one of the sacred months only. Otherwise there is no fast that is prescribed in this month, and no prayer or ‘umrah or anything else that is prescribed. It is like all other months.
{Tahdheeb at-Tahdheeb (3/305-306).
The hadeeth was classed as da‘eef by an-Nawawi in al-Adhkaar (p. 189) and Ibn Rajab in Lataa’if al-Ma‘aarif (p. 121). It was also classed as da‘eef by al-Albaani in Da‘eef al-Jaami‘ (4395).
Al-Haythami said: } It was narrated by al-Bazzaar, and its isnaad includes Zaa’idah ibn Abi ar-Ruqaad. Al-Bukhaari said: His hadeeth is odd, and a number of scholars regarded him as ignorant.\
With regard to the Muslim asking his Lord to let him reach Ramadan, there is nothing wrong with that. So we can ask Allah for the month of Ramadhan as it is a blessed month with lots of rewards.
Al-Haafiz Ibn Rajab (may Allah have mercy on him) said:
Ma‘alla ibn al-Fadl said: They used to pray to Allah for six months, may He be exalted, asking Him to cause them to reach Ramadan, and they used to call upon Him for six months asking Him to accept it from them. Yahya ibn Abi Katheer said: One of their du‘aa’s was: “O Allah, keep me safe until Ramadan, keep Ramadan safe for me, and accept it from me.”
Allah know the best
