Idraj may occur also in the midst of the hadith like hadith of Faddalah reported by al-Nasa’i that the Prophet said: “I am a za’im (guarantor of paradise) – and za’im is hamil (undertaker) – for that who believes in me and struggles on the way of Allah, with a house in the gardens of heavens”. His saying: ‘and the za’im (guarantor) is the undertaker’ is included by him into the hadith.

In regard of the inclusion at the end of the hadith, it occurred in the eclipse hadith which was recorded in the Sahih that (the Prophet said): The sun and moon are verily two signs (marvels) among God’s signs (ayat). They never eclipse because of the death or life of anyone. When you see this, betake yourselves to remembrance of Allah and prayers (salat). Al-Ghazzali says that the reporting of this addition was not confirmed, so its utterer should be belied.

Can the Fabricated Hadith be Recognized: The investigators have stated generalities through which recognizing which hadith being fabricated becomes feasible: Its contradiction to the Qur’an and authentic successive Sunnah or decisive unanimity or determined rules of the Shari’ah, or to the rational proof, or to the senses and conspicuousness and all certainties. Or the hadith’s including temerities in regard of promise and threats, reward and punishment.

Or its being contradictory to the rules brought by the clear Sunnah, or the hadith’s being invalid by itself, or its invalidity being established by correct evidences. Or the hadith’s being unlike the speech of prophets, or its being nearer to the speech of physicians, or its containing the chronicles of coming days, or its being awkward or a laughing-stock or other than this.

Among them also are those traditions on whose baselessness several veracious evidences, or established knowledge experiments, or those ones that be poor in meaning.

Ibn Hajar al-Asqallani writes: From the word ‘poor’ the meaning is intended, and whenever it is found it indicates presence of fabrication, as this religion (Islam) comprises only good points, while poorness in wording never indicates this, due to the possibility that the hadith being reported according to meaning by the narrator who might exchange its words with non-eloquent ones.

Ibn al-Jawzi said: The disapproved hadith makes knowledge-seeker shudder, with causing his heart to have aversion to it, particularly that one using the terms of the law-maker, having experience in them, their splendour and resplendence.
