O Allāh, bless us in Rajab and Sha’bān, and allow us to reach Ramaḍān

In conclusion: Since the essence of this du’ā’ is founded upon two narrators who are unacceptable, and there is no other path to strengthen this narration, then it is not correct to attribute this to be a sunnah of the Prophet (ﷺ) that is to be said when the month of Rajab enters. There is nothing wrong with a person making a du’ā’ to live and reach the month of Ramaḍān, however, the focus is on whether it is a sunnah of the Prophet (ﷺ) to do so, and this cannot be affirmed.

When is it permissible to act according to a weak ḥadīth when it comes to faḍā’il al-a’māl (virtuous deeds)?

Scholars have stipulated the conditions for acting upon aḥādīth concerning faḍā’il al-a’māl, and perhaps some did not mention it as a stipulation, but it became known from how they used it. And the conditions are:

First condition: That the ḥadīth is not ḍa’īf jiddan [extremely weak].

Second condition: That there is evidence that gives basis for the virtue that is mentioned in the ḥadīth and this ḥadīth [only] gives an addition to the virtue.

Third condition: That [the person] should not believe when performing [the deed] that it is established with certainty; rather, he holds to caution.

Performing ‘Ajn in the Prayer (which entails rising from the sujūd for the next rak’ah while making a fist with the hands and placing the knuckles on the ground to support oneself)

The weakness of this ḥadīth, however, does not affect the issue of supporting oneself with the hands when rising, only the affirmation of the ‘ajn (putting the hands in a fist-like position). As for supporting oneself with the hands when rising, then this is confirmed from the ḥadīth of Mālik ibn al-Ḥuwayrith.
