The ulama among the experts in hadith and the experts in law and others have said: it is permissible and (also) recommended that the religious practice (al-`amal) concerning good deeds and good character (al-fadâ'il), encouragement to good and discouragement from evil (al-targhib wa al-tarhib) be based (even) on weak hadith (bi al-hadith al- da`îf) as long as it is not forged (mawdu`).

Thanks for reminding; I was in fact replying to brother saalik who complained people are generally careless about this night. One can be careless if one thinks the hadith is too weak to be based upon.
