Guaranteeing someone's debt is itself a virtuous act. Kafalah is a recognised contract in Islamic law, it is treated as a form of assistance to a person in need, and a guarantor may not charge a fee for providing it precisely because it is meant to be a favour rather than a service sold. The difficulty is not the guarantee but what is being guaranteed. Standing behind an interest-bearing loan means enabling a transaction scholars prohibit and becoming a party to the documentation, and narrations name the parties to a riba contract - including those who write and witness it - as sharing in the blame. Most scholars therefore advise against guaranteeing conventional loans. There is a widely recognised exception where a family member faces genuine necessity and no alternative exists. Beyond the ruling, there is a practical warning worth stating plainly: as guarantor you owe the entire debt if the borrower defaults, and most guarantors do not realise this until they are asked to pay.

No - kafalah is a recognised contract and is regarded positively, because it lets someone who lacks standing obtain what they need on the strength of another's word. Scholars hold a guarantor may not charge a fee for it, precisely because it is meant to be assistance rather than a sold service. The difficulty is never the guarantee; it is what is being guaranteed.
Because the loan frequently does not happen without you. Narrations on riba name not only the one who consumes and the one who pays, but those who write the contract and those who witness it, describing them as equal in the matter. A guarantor is a named party who signs the agreement, and most scholars read that as reaching them.
This is the recognised exception. Where a close family member faces genuine necessity - medical treatment, housing where no alternative exists - and no permissible financing is available, many scholars permit it, combining the necessity principle with the obligation to assist relatives in hardship. The conditions are real necessity, no available alternative, and limiting it to what the situation requires.
Bounded exposure, no interest enabled
Lending the amount yourself without any increase caps your exposure at what you actually gave, rather than leaving you liable for a whole debt plus accrued charges. Interest-free lending is encouraged and carries reward.
Record the amount and repayment terms in writing, as the Quran's longest verse instructs. It protects the relationship.
